what is the square route of -4?

2i. The character "i" denotes the square root of -1, which is not a real number. So, the sq. root of -4 is 2i.

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.

It's rough, but what I would do is find the difference between the two routes on either side of the number (Wait for the example!)  and count until you get to it, then make a fraction. \n\nEXAMPLE:\nfind square root of 2.\n\n2 is between 1 and 4.\n\nit's 1 past 4 and there are 3 numbers between the two.  So root 2 is approxamately 1 1/3.  The 1 is from the first number between one and 4, and the 3 is because there's 3 numbers between 1 and 4.  It's confusing, and it's not a good estimate, but it works if you understand it.

y = -1 is a horizontal line that contains the points (n, -1)\n\nhow far is (3, 4) from that line?  Subtrace the y-coordinates: 4 - (-1) = 5

First subsitute -1 wherever you see x\n\nf(-1) = 4(-1) - 3\n      = -4 - 3\n      = -7

Focus on -(x+1).\nIt's like multiplying every term inside the bracket by -1. Hence you're going to get -x-1.\n4 - x - 1 = 8\n3 - x = 8\nAdd x to both sides: 3 = 8+x\nSubtract 8 from both sides: -5 = x\n\nHope this helps :)

(x-2)^2=x\nor x^2 - 4x + 4=x\nor x^2 - 5x + 4=0\nor x^2 - 4x - x + 4=0\nor x(x-4) - 1(x-4)=0\nor (x-4)(x-1)=0\n.'. x=4 or x=1;

False, a square is a regular polygon.  Say each side is 4 units long.  Use the pythagorean theorem to solve for the diagonal.  So 4^2+4^2=x^2, or the square root of 32 which is between 5 and 6.  The diagonal would have to be about 5.7 (mental math) which is not 4.

Use the distributive property:\n4*5x + 4*(-9) =24\n20x + -36 = 24\n      +36   +36\n20x = 60\n--------\n20    20\nx=3\nI realize you already have the answer but sometimes the path is more important than the destination...

The number is 41312432.\n\nThe "4" is in the 1st anf fifth space. 4_ _ _ _4_ _\nThe "1" is in the 2nd and 4rth space_1_ 1_ _ _ _\nThe "3" is in the 3rd and 7th space _ _ 3_ _ _3_\nThe "2" is in the 5th and 8th space_ _ _ _ 2 _ _2\n\nDon't know any way to show steps other than the way I did here...\n\nBTW the number 23421314 also satisfies the requirements.
