这道英语IQ怎么写?
if the difference of two number is 10 and their produrt is 12,what is the sum of their squares?

a-b=10
a*b=12
（a-b）∧2=100
a∧2-2ab+b∧2=100
所以a∧2+b∧2=100+2ab=100+2*12=124
a∧2+b∧2=124

x-y=10→(x－y)²=x²＋y²－2xy=100
xy=12
∴x²＋y²=100＋2×12=124

A-B=10
AB=12
一式平方后为A^2+B^2-2AB=100，二式代入，即为所求A^2+B^2=124

number->numbers, produrt->product, 不知道还有什么错误?
