Question

Rewrite the quadratic function below in standard form y=3(x+3(x+5)

Answer 1

Answer:

$\boxed {y =3 {x}^{2} + 8x + 15}$

Step-by-step explanation:

$y = 3(x + 3)(x + 5)$

Expand/Distribute x+3 in x+5

$y = 3( {x}^{2} + 8x + 15)$

Distribute 3 in the expression.

$y = 3 {x}^{2} + 24x + 45$
