Question

8. Multiply 2x(x² + 3xy + 5) and find its value for x = -2 and y = 2
​

Answer 1

Step-by-step explanation:

=2x^3 + 3x^2y + 10x

now put value of x= -2

=2(-2)^3 + 3(-2)^2y + 10(-2)

= 2(-8) + 3(4)y - 20

= -16 + 12y - 20

= 12y - 36

now put value of x=2

= 2(2)^3 + 3(2)^2y + 10(2)

= 2(8) + 3(4)y + 20

= 16 + 12y + 20

= 12y + 36
