Question

2X^+X-4=0 BY Quadratic formula ​

Answer 1

Answer:

We know,

$\:\sf{\frac{-b±√b²-4ac}{2a}}$

So,

$\:\sf{\frac{-1±√1²-4 x 2 x (-4)}{2 x 2}}$

$\:\sf{\frac{-1±√1+32}{4}}$

$\:\sf{\frac{-1±√33}{4}}$

Therefore,

x = $\:\sf\purple{\frac{-1+√33}{4}}$

or

x = $\:\sf\purple{\frac{-1-√33}{4}}$

Step-by-step explanation:
