Question

Find the product of the following pairs:
$-5t^2,-3t^2$

• A. $15t^4$
• B. $45t^4$
• C. $65t^4$
• D. None of these

Answer 1

The correct option is A $15t^4$

We multiply the given polynomials $-5t^2$ and $-3t^2$ as shown below:

$(-5t^2)\times (-3t^2)=(-5\times t\times t)\times (-3\times t\times t)=(-5\times -3)\times (t\times t\times t\times t)=15\times t^4=15t^4$

Hence, the product of $-5t^2$ and $-3t^2$ is $15t^4$.
