Question

Find the value of 4a² + 3ab + 3b² if a = 3 and b = 2

Answer 1

Answer:

→ 66

Step by step explanation:

4a² +3ab +3b²

where ,

a=3

b=2

so,

substituting the values of a and b in the given equation :

→4(3)² + 3(3)(2) + 3(2)²

→ 4×9 + 3×6 + 3× 4

→ 36+18+12

→ 66

Answer 2

4a² + 3ab + 3b² ; if a = 3 , b = 2

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

So, let's plug & solve it! 

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
