How much is x3 - 3x2 + 5x - 2 less than 3 - 2x + x2 - x3?

Question

KnowledgeBoat · Accepted Answer

Here it asks "how much is A less than B," it means B is the larger value. Therefore, we subtract A from B (B - A). ∴ Subtract (x3 - 3x2 + 5x - 2) from (3 - 2x + x2 - x3) Arranging the expressions in ascending powers of x (constant, x, x2, x3). Hence, the answer is 5 - 7x + 4x2 - 2x3
