Question

If x + y = 4, then find the value of x2 + y2 + 12xy - 64.​

Answer 1

Answer:

- 8

Step-by-step explanation:

This is given that X + Y = 4

For this we solve this equation '' X2 + y2 + 12xy - 64 ''.

So we do this like this :

2 * 2 + 2 * 2 + 12 * 2 * 2 - 64

Now you think why we write 2 and 2 but we have given 4 because this is different terms so we half this

So this come like this :

4 + 4 + 24 * 2 - 64

8 + 48 - 64

56 - 64

--> - 8 Ans.

So the answer is (-8).
