Question

factorize 2x²+x-14
please answer​

Answer 1

Answer:

This cannot be factorised.

The determinant = b² - 4 ac

= 1 - (-14)(2)(4)

= 1 + 14*8

= 1 + 112

= 113

This number is not a perfect square.

So u cant factorize it ,please give the correct question.

Step-by-step explanation:

Answer 2

Answer:

The given expression factors as $(x - \frac{-1 -\sqrt{113}}{4})(x-\frac{-1 + \sqrt{113}}{4})$

Step-by-step explanation:

$2x^2 +x -14 = 0 \text{ will give us } x = \frac{-1\pm\sqrt{(-1)^2 - 4\cdot (-14)\cdot (2)}}{2.2}\\or, x = \frac{-1\pm\sqrt{113}}{4}\\\text{Therfore, } 2x^2 +x -14 = (x - \frac{-1 -\sqrt{113}}{4})(x-\frac{-1 + \sqrt{113}}{4})$
