Answer 2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀☆ GIVEN⠀ POLYNOMIAL  – 28x² + 37x  - 21 :

⠀⠀⠀⠀

$:\implies\sf 28x^2 +37x - 21 = 0 \\\\\\\star \sf{By \:Using\:Sum-Product \:Pattern\::}\\\\ \:\implies\sf 28x^2 + 49x - 12x - 21= 0 \\\\\\\star\sf{Finding\:out\:Common\:Terms\::}\\\\\\:\implies\sf 7x(4x + 7) -3(4x + 7) = 0\\\\\\\star\sf{Now,\:Rewrite\:in\:Factored\:term\::}\\\\\\:\implies\sf (7x - 3)\; (4x + 7) = 0\\\\\\:\implies{\underline{\boxed{\frak{\purple{x \:=\:\:\:\dfrac{3}{7}\:\:\& \:\:\dfrac{-7}{4}}}}}}\;\bigstar$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm { Hence, \:The\:zeroes \:are\:\bf{ =\:\:\:\dfrac{3}{7}\:\:\& \:\:\dfrac{-7}{4} }}}}$
