Solution for =4a(2a-3) equation:


Simplifying
0 = 4a(2a + -3)

Reorder the terms:
0 = 4a(-3 + 2a)
0 = (-3 * 4a + 2a * 4a)
0 = (-12a + 8a2)

Solving
0 = -12a + 8a2

Solving for variable 'a'.
Remove the zero:
12a + -8a2 = -12a + 8a2 + 12a + -8a2

Reorder the terms:
12a + -8a2 = -12a + 12a + 8a2 + -8a2

Combine like terms: -12a + 12a = 0
12a + -8a2 = 0 + 8a2 + -8a2
12a + -8a2 = 8a2 + -8a2

Combine like terms: 8a2 + -8a2 = 0
12a + -8a2 = 0

Factor out the Greatest Common Factor (GCF), '4a'.
4a(3 + -2a) = 0

Ignore the factor 4.

Subproblem 1

Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0

Subproblem 2

Set the factor '(3 + -2a)' equal to zero and attempt to solve: Simplifying 3 + -2a = 0 Solving 3 + -2a = 0 Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2a = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 0 + -3 -2a = 0 + -3 Combine like terms: 0 + -3 = -3 -2a = -3 Divide each side by '-2'. a = 1.5 Simplifying a = 1.5

Solution

a = {0, 1.5}
