Question

(2xsquare+5) ( 3xsquare+5) ?

Answer 1

$Given \: (2x^{2} + 5 )(3x^{2} + 5 ) \\ = 2x^{2} (3x^{2} + 5 )+5(3x^{2} + 5 )\\= 2x^{2} \times 3x^{2} + 2x^{2} \times 5 + 5 \times 3x^{2} + 5 \times 5 \\= 6x^{4} + 10x^{2} + 15x^{2} + 25 \\= 6x^{4} + 25x^{2} + + 25$

Therefore.,

$\red{ (2x^{2} + 5 )(3x^{2} + 5 )}\\\green { = 6x^{4} + 25x^{2} + + 25}$
