Question

find the roots of the following quada odio
equation by applying the quadratic formulas
2x2+x=4=0.​

Answer 1

Answer:

hello again

Step-by-step explanation:

now see carefully

the quadratic equation is given by 2x^2+x-4.

see the general form of quadratic equation is ax^2+bx+c.

so, a=2, b=1, c=-4.

THE FORMULA FOR FINDING ROOTS OF A QUADRATIC EQUATION IS:-

-b+_ sq.rt (b^2-4ac)/2a.

so, it is seeming easy now,

the roots are -1+_sq.rt {(-b)2-4×2×(-4)}/2×2

=-1+_sq.rt (1^2+32)/4

=-1+_sq.rt 33/4.

now, -1 +_ root 33/4=0

so it will be either -1+root 33 or -1-root 3

hope this helps u

be happy
