sorry for being hazy I hope it helps you
3x(x+3)^2
3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x
answer
3x^3 + 18x^2 + 27x
<span>The function y = –3x² –12x + 3 is a parabola facing either upward of downward. we use completing the squares to find the vertex.
</span>y = -3(x² + 4x + 1)
(k/2)^2 = (4/2)^2 = 4
y = -3(x² + 4x + 4 + 1 - 4)
<span>y = -3(x + 2)² + 9
</span>y- 9 = <span>-3(x + 2)²
vertex is equal to at (-2,9)</span>
