Simplifying (p + 2)(p + -4) = 0 Reorder the terms: (2 + p)(p + -4) = 0 Reorder the terms: (2 + p)(-4 + p) = 0 Multiply (2 + p) * (-4 + p) (2(-4 + p) + p(-4 + p)) = 0 ((-4 * 2 + p * 2) + p(-4 + p)) = 0 ((-8 + 2p) + p(-4 + p)) = 0 (-8 + 2p + (-4 * p + p * p)) = 0 (-8 + 2p + (-4p + p2)) = 0 Combine like terms: 2p + -4p = -2p (-8 + -2p + p2) = 0 Solving -8 + -2p + p2 = 0 Solving for variable 'p'. Factor a trinomial. (-2 + -1p)(4 + -1p) = 0Subproblem 1
Set the factor '(-2 + -1p)' equal to zero and attempt to solve: Simplifying -2 + -1p = 0 Solving -2 + -1p = 0 Move all terms containing p to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -1p = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1p = 0 + 2 -1p = 0 + 2 Combine like terms: 0 + 2 = 2 -1p = 2 Divide each side by '-1'. p = -2 Simplifying p = -2Subproblem 2
Set the factor '(4 + -1p)' equal to zero and attempt to solve: Simplifying 4 + -1p = 0 Solving 4 + -1p = 0 Move all terms containing p to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1p = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1p = 0 + -4 -1p = 0 + -4 Combine like terms: 0 + -4 = -4 -1p = -4 Divide each side by '-1'. p = 4 Simplifying p = 4Solution
p = {-2, 4}
