Factor complete m2+m-20
Anna [14]
Hi there!
I'm going to assume you mean m^2 + m - 20.
The factor of this is (m + 5)(m - 4)
And I found this by finding what two numbers add to 1 and multiply to -20, which is 5 and -4.

Now if you FOIL this, (First, outer, inner, last terms) you should come to the initial equation.
(m + 5) * (m-4)
m * m = m^2
5 * m = 5m
m * -4 = -4m
5 * -4 = -20
So, in combining like terms, you'd get m^2 + 1m -20.
