3. Write the following equations in factored form. Remember to common factor first

Question

(if possible).
a) 𝑦 = 6𝑥 + 42

Answer 1

𝑦 = 6(𝑥 + 7)

b) 𝑦 = 𝑥^2 − 5𝑥 − 6

𝑦 = (𝑥 − 6)(𝑥 + 1)

c) 𝑦 = 9𝑥^2 + 15𝑥 + 6

𝑦 = 3(3𝑥 + 2)(𝑥 + 1)

d) 𝑦 = 2𝑥^3 + 4𝑥^2 − 16𝑥

𝑦 = 2𝑥(𝑥 − 4)(𝑥 + 2)

e) 𝑦 = 25𝑥^2 − 16

𝑦 = (5𝑥 + 4)(5𝑥 − 4)
