Question

(49l²-100m²)÷(7l+10m)​

Answer 1

$\huge\bold\red{Hey!}$

$( {49l}^{2} - {100m}^{2} ) \div (7l + 10m \\ ({ 7l }^{2} - {10m}^{2} ) \div (7l + 10m) \\ (7l + 10m)(7l - 10m) \div (7l + 10m) \\ (7l - 10m)$

Answer 2

$<font color=black>$

$\frac{49 {l}^{2} - 100 {m}^{2} }{7l + 10m}$

$= \frac{ {(7l)}^{2} - {(10m)}^{2} }{7l + 10m}$

$= \frac{ \cancel{(7l + 10m)}(7l - 10m)}{ \cancel{(7l + 10m)}}$

$= 7l - 10m$

$\bf\large\underline\blue{Answer:-}$

• Answer for the question is $7l - 10m$
