8x2 + 16x + 8 = 8*(x2 + 2x + 1) = 8*(x + 1)2

Please do not remove this question from Inappropriate or split any alts from it. Thanks!

15 = 8x2 - 14x; whence, 8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0. Therefore, x = 5/2 or -3/4.

It is: 25-4(8*6) = -167

You could try dividing both numerator and denominator by 8x2 .

(4x + 3)(2x - 1) so x = -0.75 or 0.5

There is no equals sign visible but, taking the equation to be8x2 + 2x + 1 = 0,the solutions are the complex conjugate pair, -1.25 Â± 0.330719*i where i is the imaginary square root of -1.

8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)

the roots are 1, - 1/3, - 3 1/2 and 3 1/2

x3 + 7x = 8x2x3 + 7x - 8x2 = 0 [subtract 8x2 from both sides]x(x2 + 7 - 8x) = 0 [factor out x]x(x-1)(x-7) = 0 [factor]Since the product of the three factors x, x-1, and x-7 equals zero, any of the three expressions could equal zero:x = 0x - 1 = 0, x = 1x - 7 = 0, x = 7Therefore, there are three solutions to the equation x3 + 7x = 8x2:x = 0x = 1x = 7Or, in set notation: x = {0,1,7}

8x2 + 2x - 1 = (4x - 1)(2x + 1).

8x2 + 6x - 9 = (2x + 3)*(4x - 3)

(3x - 1)(2x2 - 2x - 1)

8x2-16x+8=8(x-1)2 How to do it: First factor out the 8 and you have 8(x2 -2x+1) look at the 1 and not the only two way to get 1 are by multiplying -1x-1 or 1x1 Only the -1x-1 will work and give us the -2x.

10x3 + 3x2

8x2+6x-35 = (2x+5)(4x-7) when factored

7Improved Answer:8x2-18x+9 = (4x-3)(2x-3)

What are the factors? 2x3 - 8x2 + 6x = 2x(x - 1)(x - 3).

(2x + 1)(4x + 7)

8x2(x + 3)

x= 2 because 2x+4=16 4x2=8 8+2 or 8x2=16

(x+1)(x+5)(x+2)
