Question 598245: Could someone please check my work.
Evaluate each polynomial for x = 5 and y = −2.
10. x^2 + 5y^2 − 4xy
5^2 + 5(-2^2) – 4(5)(-2)
= 5^2 + 5(-4) – 4(5)(-2)
= 25 – 20 + 40
= 45
Thank you

10. x^2 + 5y^2 − 4xy
5^2 + 5((-2)^2) – 4(5)(-2)
= 5^2 + 5(4) – 4(5)(-2) (mistake made in middle term)
= 25 + 20 + 40
= 85
