$standard form is \Rightarrow x^{3} + 16 x^{2} + 85 x + 150$ $color(indigo)("standard form is " => x^3 + 16x^2 + 85x + 150$

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

$\Rightarrow (x + 6) \cdot (x^{2}^10 x + 25)$ $=> (x+6) * (x^2 ^ 10x + 25)$

$\Rightarrow x^{3} + 6 x^{2} + 10 x^{2} + 60 x + 25 x + 150$ $=> x^3 + 6x^2 + 10x^2 + 60x + 25x + 150$

$\Rightarrow x^{3} + 16 x^{2} + 85 x + 150$ $color(indigo)(=> x^3 + 16x^2 + 85x + 150$

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