Question

Find the product of (x2 + 2x −3)(4x2 − 5x + 6).

4x4 + 13x3 − 16x2 + 27x − 18

4x4 + 3x3 − 28x2 + 27x − 18

4x4 + 3x3 − 16x2 + 3x − 18

4x4 + 3x3 − 16x2 + 27x − 18

Answer 1

The product of (x2 + 2x - 3)(4x2 - 5x + 6) is 4x4 + 3x3 - 16x2 + 27x - 18

Answer 2

(x^2 + 2x - 3)(4x^2 - 5x + 6) x^2(4x^2 - 5x + 6) 4x^4 - 5x^3 + 6x^2 now the 2nd number 2x(4x^2 - 5x + 6) 8x^3 - 10x^2 + 12x now the 3rd number -3(4x^2 - 5x + 6) -12x^2 + 15x - 18 now put them all together 4x^4 - 5x^3 + 6x^2 + 8x^3 - 10x^2 + 12x - 12x^2 + 15x - 18 combine like terms 4x^4 + 3x^3 - 16x^2 + 27x - 18 <== your answer
