Question

Factorize 4x squared - 25y squared

Answer 1

`{ \qquad\qquad\huge\underline{{\sf Answer}}}`

here we go~

`\qquad \sf  \dashrightarrow \: 4x {}^(2) - 25y {}^(2)`

[ identity : a² - b² = (a + b)(a - b) ]

`\qquad \sf  \dashrightarrow \: (2x) {}^(2) - (5y) {}^(2)`

`\qquad \sf  \dashrightarrow \: (2x + 5y)(2x - 5y)`
