Question

find the value of 4x2+3xy+3y2 if x=3 and y=2

Answer 1

Hey there! :) 

4x² + 3xy + 3y² ; if x = 3 , y = 2

To find the value of this expression, we must plug in '3' for 'x' and '2' for 'y.'

So, let's plug & chug! 

4(3²) + 3(3)(2) + 3(2²)

Simplify inside the parenthesis first! 

4(9) + 3(6) + 3(4)

Simplify!

36 + 18 + 12

Simplify.

54 + 12

Simplify one last time.

66 → final answer

~Hope I helped!~ 

Answer 2

32 is the answer because
4x2 equal 8 and 3xy equal 12 and 3y2 equal 12
So 8 +12+12=32
