Question

Factorize 4x^4+7x^2-2​

Answer 1

Step-by-step explanation:

by this process we can solve it

Answer 2

$</p><p>\huge {\underline {\underline {\mathbb {\pink { ANSWER }}}}}$

$4x {}^{4} + 7 {x}^{2} - 2$

$4 {x}^{4} + 8 {x}^{2} - {x}^{2} - 2$

${4x}^{2} ( {x}^{2} + 2) - 1( {x}^{2} + 2)$

$( {x}^{2} + 2)( {4x}^{2} - 1)$

using Identity

${a}^{2} - {b}^{2} = (a+ b)(a - b)$

$( {x}^{2} + 2)(2x - 1)(2x + 1)$

hope it helps you..........
