To solve the equation, factor the left hand side by grouping. First, left hand side needs lớn be rewritten as 5x^2+ax+bx-1. Lớn find a and b, set up a system lớn be solved.
Since ab is negative, a & b have the opposite signs. Since a+b is positive, the positive number has greater absolute value than the negative. The only such pair is the system solution.
This equation is in standard form: ax^2+bx+c=0. Substitute 5 for a, 4 for b, & -1 for c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
