Question

Please please help and show work, preferably the box method!!!!

Answer 1

Answer:

$(x-2)(x+15)$

Step-by-step explanation:

$x^2+13x -30$

Find the factors that multiply to -30, but add up 13

These factors are -2, 15

$x^2-2x+15x-30$

Split the expression then factor it

$x^2-2x$ | $15x-30$

$x(x-2)$ | $15(x-2)$

Finally put it all together

$(x-2)(x+15)$

Answer 2

Answer:

(x−2)(x+15)

Step-by-step explanation:

The middle number is 13 and the last number is -30.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 13

Multiply together to get -30

Can you think of the two numbers?

Try -2 and 15:

-2+15 = 13

-2*15 = -30

Fill in the blanks in

(x+_)(x+_)

with -2 and 15 to get...

(x-2)(x+15)
