Guys i will mark as brainiest if you explain well. anyways, solve each equation by factoring. r^2+9r+8=0 so my question is how do i do this

To factor the equation, you can start by note that leading coefficient is 1 so factor would looks like (R + ?)(R + ?) = 0 because 1*1 = 1

And we know that 1*8 = 8 and 1 + 8 = 9 so then we have (R + 8)(R + 1)=0

Now we can split factors into two equations: R+8 = 0 or R+1 = 0.

Solve both equation and we get R = -8 or R = -1
