Find the value of the expression 3m² + 2p² - 15 when m = 3 and p = 10.

Solution:

Given: 3m² + 2p² - 15

When m = 3 and p = 10

Substituting the values

= 3(3)² + 2(10)² - 15

By further calculation

= 3(9) + 2(100) - 15

So we get

= 27 + 200 - 15

= 212

Therefore, the value of the expression is 212.

Find the value of the expression 3m² + 2p² - 15 when m = 3 and p = 10.

Summary:

The value of the expression 3m² + 2p² - 15 when m = 3 and p = 10 is 212.
