Question

Multiply the polynomials (2x^2+5x+5)(4x-3)

Answer 1

Answer:

${8x}^{3} + {14x}^{2} + 5x - 15$

Step-by-step explanation:

$( {2x}^{2} + 5x + 5)(4x - 3)$

$4x( {2x}^{2} + 5x + 5) - 3( {2x}^{2} + 5x + 5)$

${8x}^{3} + {20x}^{2} + 20x - {6x}^{2} - 15x - 15$

${8x}^{3} + {14x}^{2} + 5x - 15$

Answer 2

Answer:

8x³ + 14x² + 5x - 15

Step-by-step explanation:

Take each separate term in the first set of parentheses and multiply it by the expression in the second set of parentheses, put it all together, simplify, then you will have your answer. Remember, whenever you multiply, you add the exponents.
