Solve the following.
never [62]

Answer:

b.  x = 11/8, x = 59/72.

Step-by-step explanation:

4|8x - 6| = 5|-8x + 7|

square both sides:

16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)

1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0

576x^2 - 1264x + 649 = 0

x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)

x = 11/8, x = 59/72.

What are the factors of the square root of 329
Andru [333]

Answer: x=-\dfrac{3}{2}, 7

Step-by-step explanation:

2x^2-10x-26=x-5

2x^2-10x-26-x+5=0  Move all terms to one side

2x^2-11x-21=0 Simplify 2{x}^{2}-10x-26-x+5

2x^2+3x-14x-21=0 Split the second term

x(2x+3)-7(2x+3)=0  Factor out common terms in the first two terms, then in the last two terms.

(2x+3)(x-7)=0 Factor out the common term 2x+3

x=-\dfrac{3}{2}, 7
