Question

(30 points worth, pls help)

Answer 1

Step-by-step explanation:

x intercept y=0

0 = 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

Answer 2

Answer:

x intercept y=0

0

= 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

Step-by-step explanation:

0  = 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)
