solve the following quadratic equation by factoring is what the question says
First, subtract 49 from both sides, what do you get?
\[x^2-4x-45\]
Good, now what 2 numbers multiply to be -45, and add up to be -4?
x=-9 x=5

Well you would have (x-9)(x+5)=0.. so what would x be?
im not sure what to do after that
Well set both of those to =0 x-9=0 solve for x and x+5 = 0
o meaning x=9 x=-5
Yep!
