Solve this quadratic.

• b = 4/5, b = 3

• b = 4, b = -3

• b = 1/5, b = 3

• b = 4/5, b = -3

Solve:

b² - 2b - 8 = 0

• -2, 4

• -8

• ±8

• No real solution

Solve the equation using the zero product property.

6x(x - 2) = 0

• x = -1/3 or x = -2

• x = 0 or x = 2

• x = 0 or x = -2

• x = -1/3 or x = 2

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

Solve for x:

• x = (b-y) / v

• x = by - v
• x = by + v
