Question

Evaluate:
(6x² + 5x - 1)(4 - 2x³ - 4x²).​

Answer 1

Answer:

3x - y) + (2y - 2x) + (x + y)

= 3x - y + 2y - 2x + x + y

Group like terms together.

= (3x + x - 2x) + (2y + y - y)

Combine like terms.

= 2x + 2y

Answer 2

Answer:

Step-by-step explanation:

$(6x^{2} +5x -1)(4-2x^{3} -4x^{2} )\\4(6x^{2} +5x -1)-2x^{3} (6x^{2} +5x -1)-4x^{2} (6x^{2} +5x-1)\\24x^{2} +20x-4 - 12x^{5} -10x^{4} -2x^{3} -24x^{4} -20x^{3} +4x^{2} \\-12x^{5} -10x^{4} -24x^{4} -2x^{3} -20x^{3} +24x^{2} +4x^{2} +20x-4\\-12x^{5} -34x^{4} -22x^{3} +28x^{2} -4$
