Answer 1

4(x+5)(x-7) Is The FULL Factor So Your Answer Is A.

Answer 2

x + 5

Answer 3

Your Welcome :)

Answer 4

IS this the equation 4 x 2 - 8x - 140??

Answer 5

Just to be clear ;)

Answer 6

Ah ok so I found this information about the same question maybe if will help

= 4x² - 8x - 140

= 4(x² - 2x - 35)

Polynomial like : ax² + bx + c, where :
a = 1
b = - 2
c = - 35

Δ = b² - 4ac (discriminant)

Δ = (- 2)² - 4(1 * - 35) = 4 + 140 = 144 = 12²

x1 = (- b - √Δ) / 2a = (2 - 12) / (2 * 1) = -10/2 = - 5

x2 = (- b + √Δ) / 2a = (2 + 12) / (2 * 1) = 14/2 = 7


= 4(x² - 2x - 35)

= 4(x + 5)(x - 7)
