Louise begins factoring the polynomial, which has four terms. 4x3 + 12x2 + 5x + 15 4x2(x + 3) + 5(x + 3) which is the completely factored form of her polynomial? 4x2(x + 3)2 x(4x2 + 5) (4x2 + 5) (x + 3) (4x2 + 5) (x + 3)2

Louise wants to factorize completely the given polynomial

Grouping first, second terms together and third, fourth terms together

=

Taking common from first and second terms of the given expression and taking 5 common from the third and fourth terms.

=

Taking (x+3) common from the given expression,

= is the completely factored form.

8 2/3 is the answer

step-by-step explanation: just use a calculator

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
