Question

Which expression is not equivalent
to (x + 4)(x – 3)?

Answer 1

A) x² + 7x - 12 is NOT equivalent to the expression.

Explanation:

1) expand by distributing terms.

`{x }^(2) - 3x + 4(x - 3)`

2) Expand by distributing terms.

`{x}^(2) - 3x + 4x - 12`

3) Collect like terms.

`{x}^(2) + ( - 3x + 4x) - 12`

4) Simplify.

`{x}^(2) + x - 12`

The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.
