9p^2+18p=10
9p^2+18p-10=0
compare with ax^2 +bx +c
a=9, b=18, c=-10
x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29
x=+%28-18%2B-sqrt%28324%2B360%29%29+%2F+18
x1=+%28-18%2Bsqrt%28324%2B360%29%29+%2F+18
x1= 0.45297
x2=+%28-18-sqrt%28324%2B360%29%29+%2F+18
x2= -2.453

x1= 0.45297, x2= -2.453 are the roots of the equation
