To solve the equation, aspect the left hand side by grouping. First, left hand side demands to be rewritten as 3x^2+ax+bx-16. To discover a and also b, set up a mechanism to be solved.
Since abdominal muscle is negative, a and b have the the opposite signs. Since a+b is negative, the an unfavorable number has greater absolute value than the positive. List all such integer bag that provide product -48.
All equations that the kind ax^2+bx+c=0 have the right to be fixed using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula offers two solutions, one as soon as ± is addition and one as soon as it is subtraction.
This equation is in traditional form: ax^2+bx+c=0. Substitute 3 because that a, -8 because that b, and also -16 for c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Quadratic equations such together this one have the right to be resolved by completing the square. In order to complete the square, the equation must very first be in the type x^2+bx=c.
