Question

what is the answer to x squared plus four x minus 5

Answer 1

You would want to factor it out so we are looking for two numbers that multiply to 4 and add up to -5

Answer 2

x^2+5x-x-5=0
x(x+5)-1(x+5)=0
(x-1)(x+5)=0
x=1;x=-5

Answer 3

that is correct

Answer 4

okay so the correct answer would be (x+1) (x-5) ?

Answer 5

yes

Answer 6

unless you have to break it down even more and then you have x = 1 and x = -5

Answer 7

I would put both :)
