The GCF is 2, so the equation turns into 2(2x^2 + 13x -24) but I can't figure out how to do the second part.

[arctic wren]

2(2x² + 13x - 24)

So now we need to factorise 2x² + 13x - 24

I see you used the x-method

But it should be -48 and 13

[inner flame]

I've tried every factor of 24 but none of them work with m+n= b

[arctic wren]

Because in the top, you have to put a*c

[arctic wren]

It should be -48 instead of 24

[arctic wren]

In the bottom, you have to put b

[inner flame]

so I'm using the original equation?

[arctic wren]

No we're still looking at 2x² + 13x - 24

[inner flame]

just using -48 instead?

[arctic wren]

It should be like this so far

[inner flame]

ohhhhh
I think I found m and n
16 * -3 = -48
16 + -3 = 13

[arctic wren]

that's correct

[inner flame]

so now what do I do?

I use the box method right?

[arctic wren]

Not yet

Now you have to rewrite 2x² + 13x - 24 again but write bx (26x) in terms of 16 and -3

You do this by attaching an x to 16 and -3

Because 16x -3x = 13x

[inner flame]

like this?

[arctic wren]

That's right

Now you just factorise what's inside the parentheses

[inner flame]

I just have to make the binomials match now I think

so would -3 turn into positive 3?

final answer I think

[arctic wren]

You factorised it wrong

[inner flame]

oh shoot okay

[arctic wren]

Wait lemme check

[arctic wren]

But here it should say: 2(2x(x+8)-3(x**+8**))

→ 2(2x-3)(x+8)

[inner flame]

okay cool! tysm for your help!
