Solve equation by using the quadratic formula. 9x^2 + 24 x = - 16

x = -4/3 or x = -4/3

Step-by-step explanation:

Solve for x over the real numbers:

9 x^2 + 24 x = -16

Hint: | Move everything to the left hand side.

Add 16 to both sides:

9 x^2 + 24 x + 16 = 0

Hint: | Using the quadratic formula, solve for x.

x = (-24 ± sqrt(24^2 - 4×9×16))/(2×9) = (-24 ± sqrt(576 - 576))/18 = (-24 ± sqrt(0))/18 = (-24 ± 0)/18:

x = -4/3 or x = -4/3

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
