Find the product of (x2 + 2x - 3)(4x2 - 5x + 6).
The problem is based on the concept of multiplication of polynomials.
Answer: The product of (x2 + 2x - 3)(4x2 - 5x + 6) is 4x4 + 3x3 - 16x2 + 27x - 18
Let us understand how to multiply polynomials with exponents in detail.
Explanation:
When multiplying polynomials, the coefficient is multiplied with a coefficient, and the variable is multiplied with a variable.
Therefore, (x2 + 2x - 3)(4x2 - 5x + 6)
= x2(4x2 - 5x + 6) + 2x(4x2 - 5x + 6) -3(4x2 - 5x + 6)
= 4x4 - 5x3 + 6x2 + 8x3 - 10x2 + 12x - 12x2 + 15x - 18
= 4x4 + (8 - 5)x3 + (6 - 10 - 12)x2 + (12 + 15)x - 18
= 4x4 + 3x3 - 16x2 + 27x - 18
Thus, (x2 + 2x - 3)(4x2 - 5x + 6) is equal to 4x4 + 3x3 - 16x2 + 27x - 18.
