Question

8x-3y√24x² -65xy+ 21y²​

Answer 1

Answer:

x=-4 & y=3/2

Step-by-step explanation:

ATQ, 8x-3y+√24x²-65xy+21y²

Now, we a shortcut or you can say a trick. from which we can directly find the values of x & y.

for x &y

x=-1/2×coefficient of x

y=-1/2 ×coefficient of y

x = -1/2×8 =-4

y= -1/2×-3=3/2

Hence, The values of x&y are -4 & 3/2 respectively.
