Answer:
A) To factor the function f(x) = x^4 + 3x^3 - 38x^2 + 24x + 64, we can use the technique of grouping and factor by grouping:
Step 1: Group the terms in pairs:
(x^4 + 3x^3) + (-38x^2 + 24x) + 64
Step 2: Factor out the common terms from each group:
x^3(x + 3) - 2x(19x - 12) + 64
Step 3: Factor out the common factors from the entire expression:
x^3(x + 3) - 2x(19x - 12) + 64
So, the factored form of f(x) is:
f(x) = x^3(x + 3) - 2x(19x - 12) + 64
B) To factor the function f(x) = 6x^4 - 19x^3 - 2x^2 + 44x - 24, we can use the technique of grouping and factor by grouping:
Step 1: Group the terms in pairs:
(6x^4 - 19x^3) + (-2x^2 + 44x) - 24
Step 2: Factor out the common terms from each group:
x^3(6x - 19) - 2x(x - 22) - 24
Step 3: Factor out the common factors from the entire expression:
x^3(6x - 19) - 2x(x - 22) - 24
So, the factored form of f(x) is:
f(x) = x^3(6x - 19) - 2x(x - 22) - 24
