Like so:
377+935=1312

HELP PLEASE QUICKLY!!!!
solmaris [256]
Hi again!

I think I already answered this question - right ?

Ok whatever - the answer and the steps are still in my head~

x^3 - 4x² + 2x + 10 = x² - 5x - 3
Again, same thing
x^3 - 4x² + 2x + 10 -x² + 5x + 3 = 0
Now factorize
(x + 1)(x² - 6x + 13) = 0
Set factor equal to 0
x + 1 = 0 or x² - 6x + 13 = 0
x = -1

The correct option is : B

A+ Guaranteed!
