Answer 2

Thus, the value of the above polynomial is -4.

Given:

The given polynomial is $6r^2+7r-3$ and r=-1.

To find:

Find its value.

Solution:

To find the value of the above polynomial we have to follow the below steps as follows-

The given polynomial is $6r^2+7r-3$.

Putting the value of r as -1 we get-

$6r^2+7r-3 \\ 6 \times ({ - 1})^{2} + 7( - 1) - 3 \\ 6 \times 1 - 7 - 3 \\ 6 - 7 - 3 \\ = - 4$

Thus, the value of the above polynomial is -4.
