EVALUATION A AND B ANSWER THIS THANKYOU

Answer 1

Answer:

Quadratic Formula: x = −b ± √b²-4ac/2a

Specifically used for determining the x-intercepts of a quadratic (parabolic) equation.

For example: A = 1, B = 4, C = 4

x = -4 ± √4² – 4 (1)(4) / 2(1)

x = -4 ± √ 16 – 4(4) / 2

x = -4 ± √16 – 16 / 2

x = -4 ± √ 0 / 2

x = -4 / 2

x = -2
