Factor the greatest common factor from the polynomial 3x^2 + 6x -9

ryzh [129]

Answer:

$3(x+3)(x -1)$

Step-by-step explanation:

$3x^2 + 6x -9$

All the terms in this polynomial are divisible by 3. Factor 3 out of this polynomial:

$= 3(x^2 + 2x -3)$

Now, factor inside the parentheses by grouping:

$= 3(x^2 -1x+3x -3)$

We knew to split the +2x up into -1x and 3x because -1 and 3 multiply to get -3, which is the last value in the polynomial.

$= 3(x(x -1)+3(x -1))\\= 3(x+3)(x -1)$

Therefore, the final factored polynomial is $3(x+3)(x -1)$ .

Evaluate the expression if r = 12 and t = -6.<br> (t-r)/3

Lynna [10]

Answer:

-6

Step-by-step explanation:

$\frac{(t-r)}{3}$

input the numbers

$\frac{(-6-12)}{3}$

do the problem in the parentheses first

-6-12 = -18

now it becomes

$-\frac{18}{3}$

simplify and you'll get

-6

this is because -18 ÷ 3 =

-6
