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

X(x-5) = 20. All what Peta wrote is wrong.
1st he should multiply x by all elements of (x-5)==>x²-5x =20

What he has done is wrong

Answer 2

Answer:

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.
