Question

Part A;

If 2 is the equation created as the product of − 3 and 1, Which of the following is an expression for 2?

Part B;
Then complete the polynomial equation.

Answer 1

see explanation

Explanation:

y₂ = - 3 × y₁

= - 3(4x² - 5x + 1) ← distribute parenthesis by - 3

= - 12x² + 15x - 3 → (a)

B

y₁ - y₂

= 4x² - 5x + 1 - (- 12x² + 15x - 3) ← distribute parenthesis by - 1

= 4x² - 5x + 1 + 12x² - 15x + 3 ← collect like terms

= 16x² - 20x + 4
