y^2+15y=2
y^2+15y-2=0
Find the roots of the equation by quadratic formula

a= 1 ,b= 15 ,c= -2

b^2-4ac= 225 + 8
b^2-4ac= 233
x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29
x1=%28-b%2Bsqrt%28b%5E2-4ac%29%29%2F%282a%29
x1=%28-12%2B21%29%2F%282%29
x1=( -15 + 15.26 )/ 2
x1= 0.13
x2=( -15 -15.26 ) / 2
x2= -15.13
(0.13 Or -15.13)
