Answer:
2073
Step-by-step explanation:
x²+7xy²-6yx²+7x+ 15
substitute x =7 and y=10 in the above equation, we get
7²+7(7)(10)²-6(10)(7)²+7(7)+ 15
= 49 + 49*100 - 60*49 + 49 +15
= 49 + 4900 - 2940 + 49 +15
= 5013 - 2940
= 2073

Answer :
7^2 + 7×7×10^2 - 6×10×7^2 + 7×7 + 15
= 49 + 4900 - 2940 + 49 +15
4949 - 2940 + 64
= 2009 + 64 = 2073
