# What is the standard form of a polynomial (x+3)(x+4)(x+5) ?

May 29, 2018

${x}^{3} + 12 {x}^{2} + 47 x + 60$

#### Explanation:

Given-

$\left(x + 3\right) \left(x + 4\right) \left(x + 5\right)$

$\left({x}^{2} + 3 x + 4 x + 12\right) \left(x + 5\right)$

$\left({x}^{2} + 7 x + 12\right) \left(x + 5\right)$

${x}^{3} + 7 {x}^{2} + 12 x + 5 {x}^{2} + 35 x + 60$

${x}^{3} + 12 {x}^{2} + 47 x + 60$
