What are the restrictions on x in the equation $y=\frac{x+3}{x^2-16}$  ?

•  $x\ne4,-4$  

•  $x\ne0$  

•  $x\ge16$  

•  $\left(-4,4\right)$  

Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

What should you do first in solving this equation?

x² + 6x - 13 = 3

• Factor

• Write down: a = 1, b = 6, c = -13

• Subtract 3 from both sides.

• Add 3 to both sides.
