Question

subtract the product of 2 x ( 5 x minus y) from product of 3x ( X + 2 y)​

Answer 1

Answer:

The answer is

$8xy - 7 {x}^{2}$

Step-by-step explanation:

$(step1) \: 2x(5x - y) = 10 {x}^{2} - 2xy \\ (step2) \: 3x(x + 2y) = 3 {x}^{2} + 6xy \\ (step3) \: (3 {x}^{2} + 6xy) - (10 {x}^{2} - 2xy) \\ = 3 {x}^{2} + 6xy - 10 {x}^{2} + 2xy \\ = - 7 {x}^{2} + 8xy \\ = 8xy - 7 {x}^{2}$
