Question

Solve using the quadratic formula: 3x^2-5x-4=0

Answer 1

1. Factor the left side.
2. Set each factor equal to 0
3. Solve each equation.

Answer 2

So you have \[ax ^{2}+bx+c=0\] the Quadratic Formula is \[\frac{ -b \pm \sqrt{b2-4ac} }{ 2a }\], so a=3, b=-5,c=-4. Fill in and solve.

Answer 3

\[\frac{ -(-5)\pm \sqrt{(-5)^{2}-4(3)(-4)} }{2(3)}\]

Answer 4

\[(-5)\sqrt{25-48}/2(3)\]

Answer 5

\[(-5)\pm \sqrt{25--48}/2(3)\]
