Question

1, 100a^{2 _}(a²+25)²

2, x²- 4 xy +4y² --3-36-36z²

Answer 1

\(100a^2-\left(a^2+25\right)^2=\left(10a\right)^2-\left(a^2+25\right)^2\)

\(=\left(10a+a^2+25\right)\left(10a-a^2-25\right)=-\left(a+5\right)^2\left(a-5\right)^2\)

2. viết lại đề

Answer 2

1) \(100a^2-\left(a^2+25\right)^2\)

\(=\left(10a\right)^2-\left(a^2+5^2\right)^2\)

\(=\left(10a-a^2+5^2\right).\left(10a+a^2+5^2\right)\)

\(=\left(10a-a^2+25\right).\left(10a+a^2+25\right)\)

Chúc bạn học tốt!
