Question

012. Multiply x + 2y by x-2xy + y and find the value of the product for x = 1 and y=-1

​

Answer 1

Answer:

2

Step-by-step explanation:

If x = 1 , y = -1 then,

x+2y × x-2xy+y = 1+2×(-1) × 1-2×1×(-1)+(-1)

By BODMAS Rule we should multiply first

so, 1+2×(-1) × 1-2×1×(-1)+(-1)

= 1-2× 1-2-1

= -1×-2

= 2
