If 5x^2 + 7x = 6, which statement is correct?
a) x = 2 or x = 3/5
x = -2 or x = 3/5
x=2 or x= -3/5
x=-2 or x =-3/5

12x^2=6

Divide by 12

x^2=1/2or.5

square root

x=0.707

Step-by-step explanation:

A) (-2x + 3 )(8x + 1)

B) x-int. = -1/8, 3/2

C) parabola that opens down, left end goes to -∞, -∞

right end goes to ∞, -∞

D) I would graph the 2 x-intercepts and then the max point by using    

x=-b/2a and then plugging that answer in to get y (0.688, 10.563)

Step-by-step explanation:

-16x² + 22x + 3

(-2x + 3 )(8x + 1)
