15x^2 + 28x + 5 = 0\n\n(5x + 1)(3x + 5) = 0\n\n5x + 1 = 0                        \n5x = -1                             \nx = -1/5         \n\n3x + 5 = 0\n3x = -5\nx = -5/3

x≠０\ncuz if x=0, (x-7)/x^3 is meaningless

here are the answers:\n-17x-19 for the first one \n22x+1 for the second one\n-6x^2+3x+15 for the third one, which can also be written as -3(2x^2-x-5)

yes, 2(3)+5(-5)=-19 .... 6+(-25) = -19 .... -19 = -19\n\nthe ordered pair 3 is the x variable and 5 is the y variable so just substitute to check the answer

x={-(-4) (+/-)√[(-4)^2 - 4(1)(-5)]}/(2(1))\n x= 4(+-)6/2\n x=5,   x=-1\n\nCheck:\n with x=5,  5^2-4(5)-5=25-20-5=0  OK\n with x=-1   (-1)^2 -4(-1) -5 = 1+4-5=0  OK

Plug in each of the four answers.  The only one that works is (2), because you get\n\n | 3 (-2/3) - 3 | = 5\n | -2 - 3 | = 5\n | -5 | = 5\n 5 = 5

(x-2)/(x^2-2x-15)+(x+2)/(5-x)\n(x-2)/((x+3)(x-5))+(x+2)/(5-x)\n(x-2)/((x+3)(x-5))+(-2-x)(x+3)/(x-5)(x+3)\n\n[(x-2) + (x+3)(-2-x)] / [(x+3)(x-5)]\n\nANSWER :\n(x^2+4x+8)/((x+3)(5-x))

x= 5\n\n21x+28=16x+40+13\n21x+28=16x+53\n      25=5x\n        5=x

The answer is always x=17

5 > x+1/-3 > 0\n5 > x-1/3 > 0\n5 1/3 > x > 1/3

C is correct but not complete... only the 3 is factored out... the real answer would be:\n\n3(x-1)(x+4)

You have to do the Trick, meaning you take out the 5 and reapply it to the number without the variable (2). This leaves you with: 5(xsquared-3x-10)=0\n\nFactor what is inside the parenthesis and get: (x+2)(x-5)\n\nThen reapply the 3 into the equations (but only into the variables, because your doing the trick) and you get:\n(5x+2)(5x-5)=0\n\nThen, set both equations to 0 and solve.\nThe first equation:5x+2=0\nSubtract the 2 from both sides to get: 5x=-2\n\nNext, divide the 5 out of both sides to get: x=-2/5\n\nThe second equation: 5x-5=0\nAdd 5 to both sides to get: 5x=5\n\nNext, divide the 5 out of both sides to get: x=5/5 or x=1\n\nFINAL ANSWERS:\nx=-2/5\nx=1\n\nIf it's a word problem and you can only have one answer, elimate the one that doesn't make sense. For example, if they are asking for the height of something, you wouldn't pick the negative number.

you must include x=0.

X = (0*Y) -5\nY = 0 * X\n\nbut basically just write X = -5 and thats it

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
