Question

consider the following quadratic equation:
4x^2+9x-13=-4
using the standard form ax^2+bx+c=0 of the quadratic equation above, factor the left hand side equation into two linear factors

Answer 1

\[4x^2+9x-9=0\]
\[(x+3)(4x-3)=0\] etc

Answer 2

D=81+144=225
x1=(-9+15)/8=3/4
x2=(-9-15/8)=-3
