Solve the equation:
4x2+2x - 6 = 0

x = 1 & -1.5

x = -1 & 1.5

x = (-2 ±√92)/8

x = (-2 ± √100)/8

Which of the following represents the first step in solving:

y = x2 + 3x - 5

y = x + 3

x2 - 3x + 5 = x - 3

x2 + 3x - 5 = x + 3

x2 + 3x - 5 + x + 3 = 0

x2 + 3x - 5 = 0

Determine if the point (2,0) is a solution to the following system:

y=2x - 4

y=x2 - 4

Yes, because it works in one equation.

Yes, because it works in the both equations.

No, because it works in neither equation.

No, because it works in only one equation.
