pls ans the following fast

Answer 1

Hello Friend ✌
Here is u r Ans ➡


✔1) ➡
$(4x - 5y)(4x + 5y)$


✔2) ➡
$2x {}^{2} - 50$

$= 2(x {}^{2} - 25)$

$= 2(x - 5)(x + 5)$



✔3) ➡
$x {}^{2} - y + xy - x$

$= x(x + y) - (x + y)$

$= (x + y)(x - y)$



✔4) ➡
$xy - ba + by - xa$

$= y(x + b) - a(b + x)$

$= (x + b)(y - a)$



✔5) ➡
$(a + b - 6)(a + b + 6)$



✔6) ➡
$(4x - 1)(4x + 1)$



✔7) ➡
$(1 - 8b)(1 + 8b)$



✔8) ➡
$(16a {}^{4} - 81b {}^{4} )$
$= (4a {}^{2} - 9b {}^{2} )(4a {}^{2} + 9b {}^{2} )$
