Factorize `9x^2 -22x+8`. |
|
Answer» The given expression is `9x^2-22x+8`. Here , ` 9xx 8 =72` We split -22 into two parts whose sum is -22 and product 72. Clearly, `(-18)+(-4)=-22 and (-18)xx (-4) =72` `therefore 9x^2-22x+8=9x^2-18x -4x +8` ` =9x(x-2)-4(x-2)` `=(x-2)(9x-4)`. Hence , `(9x^2-22x+8) =(x-2)(9x-4)`. |
