factor the quadratic expression: (make sure there are no spaces in your answer.)
x² + 7x + 12

Explanation:

Step1: Find factor pairs of 12

Look for two numbers that multiply to $12$ and add to $7$: $3$ and $4$ (since $3\times4=12$ and $3+4=7$).

Step2: Write factored form

Express the quadratic as a product of two binomials using the found numbers.
$x^2+7x+12=(x+3)(x+4)$

Answer:

$(x+3)(x+4)$
