Question

PETA attempted to solve the following equation. Explain PETA’s error.

X(x-5) =20
X=20 and x-5=20
X=20 and x=25

Answer 1

The answer is 15

Answer 2

Peta can only use the zero product property when the product of factors is equal to zero.

Peta must multiply x by (x - 5).

Peta must write the equation in standard form, then factor the expression.

Each factor must be set equal to zero, not 20.
