Question

what is the solution set x^2+5x-6=0

Answer 1

un-foil it what multiplys to get -6 and also adds to 5

Answer 2

at this point if you can't find the numbers then use the quadratic equation.
\[ax^2 +bx+c\]

plug the variables a, b and c into the equation.

\[\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

Answer 3

what are 2 numbers that, when multiplied equal to -6, but when added equal to +5?
those 2 numbers are 5 and -1. so
(x-1)(x+5)=0
now we have 2 solutions.
x-1=0
x=1
and
x+5=0
x=-5.

Answer 4

not 5 and -1. Its 6 and -1.
