Question

if a=
(i) 4a-4b-5-8-x multiple​

Answer 1

Answer:

$(a + \frac{2}{7} {b}^{2} )(7a - {b}^{2} )$

$7 {a}^{2} - a {b}^{2} + 2a {b}^{2} - \frac{2}{7} {b}^{4}$

$7 {a}^{2} + a {b}^{2} - \frac{2}{7} {b}^{4}$

$\frac{49 {a}^{2} + 7a {b}^{2} - 2 {b}^{4} }{7}$

$\frac{1}{7} ({49 {a}^{2} + 7a {b}^{2} - 2 {b}^{4} })$
