Question 66 (f)

Find the value of the given polynomial at a = -2 and b = 3.

$\frac{a^{2} - b^{2}}{3}$

Open in App

Solution

Given, a = -2 and b = 3
So, putting a = -2 and b = 3 in the given expression, we get
$\frac{a^{2} - b^{2}}{3} = \frac{(- 2)^{2} - (3)^{2}}{3} = \frac{4 - 9}{3} = \frac{- 5}{3}$
