Question

5(49^2+ 56xy + 16y^2)÷
10(7x + 4y)​

Answer 1

Answer:

$\frac{7x + 4y}{2}$

Explanation:

$\frac{5( {49x}^{2} + 56xy + {16y}^{2} )}{10(7x + 4y)}$

$using \: identity \: {a}^{2} + 2ab + {b}^{2} = {(a + b)}^{2}$

${49x}^{2} + 56xy + {16y}^{2} = ( 7x + 4y) {}^{2}$

$\frac{5(7x + 4y) {}^{2} }{10(7x + 4y)} = \frac{7x + 4y}{2}$
