Find the value of the following polynomial at a = - 2 and b = 3: (a² + b²)/3

Solution:

The given polynomial is (a² + b²)/3

We have to find the value of the polynomial at a = -2 and b = 3.

a² = (-2)² = 4

b² = (3)² = 9

a² + b² = 4 + 9

= 13

Now, (a² + b²)/3 = 13/3

Therefore, (a² + b²)/3 = 13/3

✦ Try This: Find the value of the following polynomial at a = -3 and b = 3: (a² + b²)/3

Given, the polynomial is (a² + b²)/3

We have to find the value of the polynomial at a = -3 and b = 3.

a² = (-3)² = 9

b² = (3)² = 9

a² + b² = 9 + 9

= 18

Now, (a² + b²)/3 = 18/3 = 6

Therefore, (a² + b²)/3 = 6
