Question

Factorise: 8x⁴+ 14x²-4​

Answer 1

8x⁴ + 14x² - 4

8x⁴ + 16x² - 2x² - 4

8x²(x² + 2) - 2(x² + 2)

(x² + 2) (8x² - 2)

Answer 2

${8x}^{4} + {14x}^{2} - 4 = 0 \\ {8x}^{4} + {16x}^{2} - {2x}^{2} - 4 = 0 \\ {8x}^{2} ( {x}^{2} + {2x}^{2} ) - 2( {x}^{2} + 2) = 0 \\ ( {8x}^{2} - 2)( {x}^{2} + {2x}^{2} )$

hope it helps you ✌️✅✅✅
