Answer: (3x − 4)(x + 1)
Step-by-step explanation:
Factoring is method to split an expression in simplest form.
Here the given expression is,
\(3x^2-x-4\)
By middle term splitting,
\(=3x^2-4x+3x-4\)
\(=x(3x-4)+1(3x-4)\)
\(=(x+1)(3x-4)\)
\(\implies 3x^2-x-4=(3x-4)(x+1)\)
Hence, fourth option is correct.
