# How do you multiply (x + 4)(x2 - 3x + 2)?

Jun 6, 2018

Multiplying this would give us: ${x}^{3} + {x}^{2} - 10 x + 8$
So you need to use the distributive property meaning that whatever is inside the first set of parentheses ($x + 4$) must get multiplied by whatever is in the other set of parentheses.
$\left(x + 4\right) \left({x}^{2} - 3 x + 2\right)$
${x}^{3} - 3 {x}^{2} + 2 x + 4 {x}^{2} - 12 x + 8$ -Distribute and combine like term
${x}^{3} + {x}^{2} - 10 x + 8$
