what would 2x - 7 = -4x -1 be?
822098
2x - 7 = -4x - 1\n\nFirst, add 4x to both sides\n\n2x + 4x -7 = -1\n\nAdd like terms\n\n6x -7 = -1\n\nAdd 7 to both sides\n\n6x = 6\n\nDivide both sides by 6\n\nx = 1

x^2 + 4x + 4 = 7 (subtrat 7 from both sides)\n\nx^2 + 4x -3 = 0 (use the quadratic equation formula)\n\n-b + or - the square root of (b^2 - 4ac) / a^2\n\n-4 + or - the square root of 16 - (4) (1) (-3) / 2\n\n-4 + or - the square root of 28 / 2\n\n-4 + or - (the square root of 4) (the square root of 7) / 2\n\n-4 + or - 2 (the square root of 7) / 2 (simplify by dividing 2 into  the -4 and 2 on the top to get rid of the 2 on the bottom)\n\nthat gives you x = - 2 + or - the square root of 7.

5x + 10 + 7x - 14 = -2x\n\n12x -4 = -2x\n\n14x = 4\n\nx = 4 / 14 = 2 / 7  (not 2/17)

4x + 8 = 9x -7\n\nTerms can be moved from one side of the equation to the other side providing you change their sign. This is called transposition.\n\nSo move the + 4x from the left side to the right side and make it a - 4x, giving:\n8 =9x -4x -7\n\nNow move the -7 from the right side to the left side and make it a +7, giving:\n8+7 = 9x-4x\nNow collect like terms giving:\n15 =  5x\nNow divide each side of the equation by 5, giving\n3=x\nDividing both sides by 5 is called the Division axiom and is true unless you divide by 0 which is undefined and not allowed.

Multiply each term in the first () by each term in the second ():\n\n2x times 2x = 4x^2\n2x times 1 = 2x\n-3 times 2x = -6x\n-3 times 1 = -3\n\nThen combine 2x and -6x\nAnswer: 4x^2 - 4x - 3

x=5x-y\n\nx-5x=-y\n\n-4x=-y\n\ndivide both sides by -4\n\n(-4/-4)x=(-y/-4)\n\n1x=(1/4)y\n\nx=y/4

complete the square:\n\ny= -2x^2-4x-7\n\ny= -2(x^2 + 2x + 7/2)\ny = -2(x^2 + 2x + 7/2) + -2(-5/2) + 2(-5/2)\ny = -2(x^2 + 2x + 7/2 -5/2) + 2(-5/2)\ny = -2(x^2 + 2x + 1) - 5\ny = -2(x + 1)^2 -5\n\nThe other way to do it is to use the formula:\nax^2 + bx + c = a(x + (b/2a))^2 + c - (b^2/4a)\n\nwhich also yields -2(x + 1)^2 - 5.\n\nYour answer is correct.

x^2-5x-14=0\n=>x^2-7x+2x-14=0\n=>x(x-7)+2(x-7)=0\n=>(x-7)(x+2)=0\nTherefore either x-7=0 or x+2=0\nIf x-7=0,then x=7,and if x+2=0,then x=_2\nThereforex=7 or -2 ans

i don't fucking know.\n\nEDIT: waitaminnit i'm gonna give it a try!\n\nx^3-4x^2-7x+10 = 0\n\nfor x = -1\n-1 -1 +7+10 != 0\nso x != -1\n\nfor x = 1\n1-1-7+10 != 0\nso x != 1 either!! ...goshdarnit.\n\nx^3-4x^2-7x+10 = 0\nx(x^2-4x) - 7x = -10\nx^2-4x - 7 = -10/x (we divided both sides by x)\n..ok...i think i've lost the plot sorry.

1/x+3/x+2=7\nMultiply by x getting:\n1+3+2x =7x\n4-5x =0\n0x* -5x +4 =0\n\n7/2x+2/x-1=4\nMultiply by 2x getting:\n7 +4 -2x =8x\n11-10x = 0\n0x* -10x +11 = 0\n\nx*+7x+2=2x+4\nx* +7x -2x +2 -4=0\nx* +5x -2 = 0\n\n4x*-3x=2x*+7 \n4x* -2x*-3x -7 =0\n2x*-3x-7 =0\n\n2x+3/x-1=x/4\nMultiply by x getting:\n2x* +3 -2x = x*/4\n2x* - x*/4 -2x +2=0\n2.25x* -2x +2 = 0\n\nThere, its done simply by multiplying and transposing terms to get what you want. You can move any term from one side of the equation to the other as long as you change its sign fro minus to plus or plus to minus.
