Question

I need to know if it’s A B C OR D

Answer 1

The equation is given as,

`6x^2-x-15=\text{ 0}`

In order to use the decomposition or factoring by grouping method the two terms are to be considered as follows:

`\begin{gathered} 6x^2-x-15=0 \\ 6x^2-10x+9x-15=0 \\ 2x(3x-5)-3(3x-5)=0 \\ (2x-3)(3x-5)=0 \end{gathered}`

Thus the two factors to be considered are -10x + x.
