$(3x { }^{2} + 4x - 8)and(5x - 7)$


​

Answer 1

Answer:

$- (15 {x}^{3} - x^(2) - 60x + 56)$

Step-by-step explanation:

[tex](3x^{2} + 4x - 8)(5x - 7) \\ 15 {x}^{3} + 20x^(2) - 40x - 21 {x}^{2} + 28x + 56 \\ 15{x}^{3} x^(2) - 60x + 56

Answer 2

Step-by-step explanation:

=> (3x²+4x-8) (5x-7)

=> 5x ( 3x²+4x-8) -7 (3x²+4x-8)

=> 15x³+20x²-40x-21x²-28x+56

=> 15x³-x²-68x+56
