Quadratics: Root Values using Binomials, Vertex using Roots

f(x) = (x - 5)(x + 1)

What is the equivalent Quadratic Equation after doing FOIL?

• x^2 - 4x - 5

• x^2 + 6x - 5

• x^2 - 5x - 4

• x^2 - 4x - 4

Simplify

(p − 8)²

What is the equivalent Quadratic Equation and the ONE x-intercept since both binomials are the same?

Hint: (p − 8)² = (p − 8)(p − 8)

• p ² − 16p − 64 and x-intercept of 8

• p ² + 16p + 64 and x-intercept of -8

• p ² − 16p − 8 and x-intercept of -8

• p ² − 16p + 64 and x-intercept of 8

Simplify using FOIL and identify the zeros:

(x - 9)(x - 7)

• x² - 2x - 63 and -9 and -7

• x² - 16x - 63 and 9 and 7

• x² - 2x + 63 and -9 and -7

• x² - 16x + 63 and 9 and 7

Find the product:

(3x – 1)(x + 5)

• 3x² + 4x + 5

• 3x² + 4x - 5

• 3x² + 14x - 5

• 3x² + 14x + 5
