Answer 1

Hello!

Answer:

`\Large \boxed{\sf -p^2}`

Explanation:

→ We want to simplify this expression:

`\sf 2p^2-q^2-3* p* p+q* q`

◼ Simplify the multiplications:

`\sf 2p^2-q^2-3p^2+q^2`

◼ Order the expression:

`\sf 2p^2-3p^2-q^2+q^2`

◼ Combine like terms:

`\sf -p^2-0`

◼ Simplify the expression:

`\boxed{\sf -p^2}`

Conclusion:

The expression 2p² - q² - 3 × p × p + q × q is equal to -p².
