Answer:
x³ - 5x² + 8x - 6
Step-by-step explanation:
(x² - 2x + 2)(x - 3) ← product is required
Each term in the second factor is multiplied by each term in the first factor , that is
x²(x - 3) - 2x(x - 3) + 2(x - 3) ← distribute all 3 parenthesis
= x³ - 3x² - 2x² + 6x + 2x - 6 ← collect like terms
= x³ - 5x² + 8x - 6 → (b)
Answer:
g( x)^2=x^2-6x+9=f(x)-4x+7, f(x)=g(x)^2-4g(x)-5=(g(x)-2)^2-9=(g(x)+7)×(g(x)-11)
f(x)=x^2-2x+2=g(×)^2+4x-7
