Question

which of these is obtained by factorizing the polynomial 10x²-9x+2? 4 points (a) (2x-1)(5x-2) (b)(2x-1)(5x+2) (c)(2x+1)(5x+2) (d)(2x+1)(5x-2)​

Answer 1

Answer:

(A)(2x-1)(5x-2)

Answer 2

Answer:

$\mathrm{Factor\:10x^2-9x+2:\quad \left(5x-2\right)\left(2x-1\right)}$

Step-by-step explanation:

$\mathrm{10x^2-9x+2}$

$=\left(10x^2-4x\right)+\left(-5x+2\right)$

$=2x\left(5x-2\right)-\left(5x-2\right)$

$\mathrm{Factor\:out\:common\:term\:}5x-2$

$=\left(5x-2\right)\left(2x-1\right)$
