Question 196360
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6x(x -1) = 12 - 20x]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6x^2 - 6x - 12 + 20x = 0]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6x^2 + 14x - 12 = 0]


Now factor the trinomial.


Hint:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6 \times 1 = 6]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (6 \times 3) + (1 \times -4) = 14]


and


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3 \times -4 = -12]
