Question

if x+y= 3x^2 +y^2=5, then xy is ​

Answer 1

Answer:

Step-by-step explanation:

x+y=3

x=3-y

putting the value of x

in this

x²+y²=5

(3-y) ²+y²=5

9-6y+y²+y²=5

2y²-6y+9-5=0

2y²-6y+4=0

2y²-4y-2y+4=0

2y(y-2)-2(y-2)=0

(2y-2) (y-2) =0

2y-2=0 or y-2=0

y=1 or y=2

so x=2 or 1

so x×y=2×1 or 1×2=2

Answer 2

X + y = 3x^2 + y^2
Then x * y = 3x^2 * y^2
3x^y^2
