Solution for 0=4p(p+9) equation:


Simplifying
0 = 4p(p + 9)

Reorder the terms:
0 = 4p(9 + p)
0 = (9 * 4p + p * 4p)
0 = (36p + 4p2)

Solving
0 = 36p + 4p2

Solving for variable 'p'.
Remove the zero:
-36p + -4p2 = 36p + 4p2 + -36p + -4p2

Reorder the terms:
-36p + -4p2 = 36p + -36p + 4p2 + -4p2

Combine like terms: 36p + -36p = 0
-36p + -4p2 = 0 + 4p2 + -4p2
-36p + -4p2 = 4p2 + -4p2

Combine like terms: 4p2 + -4p2 = 0
-36p + -4p2 = 0

Factor out the Greatest Common Factor (GCF), '-4p'.
-4p(9 + p) = 0

Ignore the factor -4.

Subproblem 1

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

Subproblem 2

Set the factor '(9 + p)' equal to zero and attempt to solve: Simplifying 9 + p = 0 Solving 9 + p = 0 Move all terms containing p to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + p = 0 + -9 Combine like terms: 9 + -9 = 0 0 + p = 0 + -9 p = 0 + -9 Combine like terms: 0 + -9 = -9 p = -9 Simplifying p = -9

Solution

p = {0, -9}
