Answer:

hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Explanation:

Simplifying

(2d + -3)(2d + -3) = 0

Reorder the terms:

(-3 + 2d)(2d + -3) = 0

Reorder the terms:

(-3 + 2d)(-3 + 2d) = 0

Multiply (-3 + 2d) * (-3 + 2d)

(-3(-3 + 2d) + 2d * (-3 + 2d)) = 0

((-3 * -3 + 2d * -3) + 2d * (-3 + 2d)) = 0

((9 + -6d) + 2d * (-3 + 2d)) = 0

(9 + -6d + (-3 * 2d + 2d * 2d)) = 0

(9 + -6d + (-6d + 4d2)) = 0

Combine like terms: -6d + -6d = -12d

(9 + -12d + 4d2) = 0

Solving

9 + -12d + 4d2 = 0

Solving for variable 'd'.

Factor a trinomial.

(3 + -2d)(3 + -2d) = 0

Subproblem 1

Set the factor '(3 + -2d)' equal to zero and attempt to solve:

Simplifying

3 + -2d = 0

Solving

3 + -2d = 0

Move all terms containing d to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + -2d = 0 + -3

Combine like terms: 3 + -3 = 0

0 + -2d = 0 + -3

-2d = 0 + -3

Combine like terms: 0 + -3 = -3

-2d = -3

Divide each side by '-2'.

d = 1.5

Simplifying

d = 1.5

Subproblem 2

Set the factor '(3 + -2d)' equal to zero and attempt to solve:

Simplifying

3 + -2d = 0

Solving

3 + -2d = 0

Move all terms containing d to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + -2d = 0 + -3

Combine like terms: 3 + -3 = 0

0 + -2d = 0 + -3

-2d = 0 + -3

Combine like terms: 0 + -3 = -3

-2d = -3

Divide each side by '-2'.

d = 1.5

Simplifying

d = 1.5

Solution

d = {1.5, 1.5}
