Question

If x=2 and y = (-1 )
so 2x³-x²y²+3​

Answer 1

Step-by-step explanation:

Given that :x=2 and y=(-1)

• =2x^3-x2y2+3
• =2×(2)^3-(2)^2(-1)^2+3
• =2×8-4+3
• =16-4+3
• =19-4
• =15

Answer 2

Answer:

15

Step-by-step explanation:

X=2,Y=-1

2X^3-X^2Y^2+3

=2(2)^3-(2)^2(-1)^2+3

=2(8)-(4)(1)+3

=16-4+3

=16-1

=15
