a^2-12a+35=0
(a-7)(a-5)=0
a-7=0
a=7 ans.
a-5=0
a=5 ans.

 Solved by pluggable solver: SOLVE quadratic equation with variable Quadratic equation (in our case ) has the following solutons: For these solutions to exist, the discriminant should not be a negative number. First, we need to compute the discriminant : . Discriminant d=4 is greater than zero. That means that there are two solutions: . Quadratic expression can be factored: Again, the answer is: 7, 5. Here's your graph:
