Determine the values of
a, b, and c for
the quadratic equation:
4x² – 8x = 3
*remember right side should =0

a = 4, b = -8, c = 3

a = 4, b =-8, c =-3

a = 4, b = 8, c = 3

a = 4, b = 8, c = -3

Solve for x. Round to the nearest hundredth if necessary.

3x² = 16x + 12

x = -0.67 and x = 6

x = -6 and x = 0.67

x = 3.33 and x = 18

x = -3.33 and x = 18

Use the Zero Product Property to solve for the values of x.

$\left(x+2\right)\left(x-3\right)=0$

x = 2 and x = 3

x = -2 and x = -3

x = 2 and x = -3

x = -2 and x = 3

Solve using the Zero Product Property:
$\left(3x+2\right)\left(x+1\right)=0$

$x=1,\ x=\frac{2}{3}$

$x=-1,\ \ x=-\frac{2}{3}$

$x=2,\ x=1$

$x=-1,\ \ x=\frac{2}{3}$
