Best ResponseYou've already chosen the best response.0you can factorise it... or use the general quadratic formula. here is a fail safe method for factorising for a quadractic \[ax^2 + bx + c = 0\] multiply a and c in your question 2 x 15 = 30 find the factors of 30 that add to 1...... 6 and 5 then set up the solution in this manner (ax + factor 1)(ax + factor2) (2x  6)(2x +5)  =0  = 0 a 2 remove any common factors from the binomials 2(x  3)(2x + 5)  =0 2 and wow there is a common factor that cancels... and leaves you with a factorised quadratic. and allow you to find the zeros.
