Khan Academy Factor using polynomial division
The polynomial p(x) = x3 + 7x2 – 36 has a known factor of (x + 3).
Rewrite p(x) as a product of linear factors.
p(x)=

p(x) as a product of linear factors.

Step-by-step explanation:

(x+3) is the factor of polynomial

So, we can divide by (x+3) to find other factors

The division is shown in figure attached.

The quotient is: x^2+4x-12

Now factoring the quotient to find linear factors

The factors are

So, p(x) as a product of linear factors.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
