Question

Factorise


1) 8x² - 14x - 9

2) x²-y²-z²+2yz
​

Answer 1

$\large\underline\bold{ANSWER \red{\huge{\checkmark}}}$

$\star\:\: 8x^2-14x-9$

$\implies 8x^2+4x-18x-9$

$\implies 4x(2x+1)-9(2x+1)$

$\implies (4x-9)(2x+1)$

$\large{\boxed{\bf{ \star\:\: (4x-1)(2x+1)\:\: \star}}}$

$\star \:\: x^2-y^2-z^2+2yz\\ \therefore cannot\:be\:factorized\: \\REASON\: :- \: IT\: DOESN'T\: CONTAIN\:ANY\:LIKE\:TERMS.$
