2-122.
Rewrite showing (2x − 3)2 as a product.
(2x − 3)(2x − 3) + 5
Multiply using a generic rectangle.
Simplify the expression.
(4x2 + (−6x) + (−6x) + 9) + 5
(4x2 + (−12x) + 9) + 5
Simplest Expression: 4x2 − 12x + 14
Start by writing the expression in the long form.
Regroup using the Associative and Commutative properties of multiplication.
