# What is the standard form of y= (x +6)(x + 5)^2 ?

Apr 19, 2018

color(indigo)("standard form is " => x^3 + 16x^2 + 85x + 150

#### Explanation:

$y = \left(x + 6\right) \cdot {\left(x + 5\right)}^{2}$

$\implies \left(x + 6\right) \cdot \left({x}^{2} ^ 10 x + 25\right)$

$\implies {x}^{3} + 6 {x}^{2} + 10 {x}^{2} + 60 x + 25 x + 150$

color(indigo)(=> x^3 + 16x^2 + 85x + 150
