Question

GuYS PLEASE HELP 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 PLEASE HELP

Answer 1

I will try my best to assist you with your problem.

We need to factor the equation,  so you must 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: either R+8 = 0 R+1 = 0.

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

Hope I helped!

Good Luck!
