What should you do first in solving this equation?

Check all that apply:

x² + 6x - 13 = 3

• Find the factors that multiply to -13, and add to 6

• Write down: a=1, b=6, c=-13
• Make it equal to 0 by subtracting 3 from each side

• Rearrange it into standard form

Determine the values of a, b, and c for the quadratic equation:  4x² – 8x + 6 = 2

• a = 4, b = -8, c = 2

• a = 4, b =-8, c = 4

• a = 4, b = 8, c = 6

• a = 4, b = 8, c = 4

Solve for the values of x:
(x + 2)(x - 3) = 0

• (2 , 0) & (3 , 0)

• (-2 , 0) & (-3 , 0)

• (-2 , 0) & (0 , 3)

• (-2 , 0) & (3 , 0)
