Solve by factoring: x^2 + 5x = −6

Question

Please help! I have a test next week and this is one of the practice problems and I do not understand this. I will not graduate unless I get a C. Please, Please!! Thank you

Answer 1

first of all, if you are going to factor an equation, get the RS equal to zero
x^2 + 5x + 6 = 0

Now can you think of 2 number, which when multiplied gives you 6, and which when added give you 5 ??
How about 2 and 3 ---> 2+3 = 5 and 2x3 = 6

so (x-2)(x-3) = 0
then x-2=0 or x-3 = 0
x = 2 or x = 3

Just an observation here, but you are not going to get any easier question along this topic than your question. You will just HAVE TO know how to do these.
