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

= -5

Now, (a² - b²)/3 = -5/3

Therefore, (a² - b²)/3 = -5/3

✦ 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

= 0

Now, (a² - b²)/3 = 0/3

Therefore, (a² - b²)/3 = 0
