You can put this solution on YOUR website!
15x%5E2%2B13x-2=0
(15x-2)(x+1)=0
15x-2=0
15x=-2
x=-2/15
x=1=0
x=-1
4x%5E2%2B19x=5
4x^2+19x-5=0
(4x-1)(x+5)=0
4x-1=0
4x=1
x=1/4
x=5=0
x=-5
6x%5E2%2B17x=3
6x^2+17x-3=0
(6x-1)(x+3)=0
6x-1=0
6x=1
x=1/6
x=3=0
x=-3
I'll leave the remainder for you to practice with.
4a%5E2-12a=-5
49y%5E2%2B25=70y
2x%5E2%2B7x=15
x%5E2-10x=-2
