Question

Find the roots of the quadratic equations by applying the quadratic formula 2x^2+x-4=0​

Answer 1

Answer:

APPLY THE FORMULA

WITHOUT FORMULA WE CAN'T GET PERFECT ROOT FOR THIS QUADRATIC EQUATION.

AND THE FORMULA IS ::

---b +/- √ b²-4ac and whole divided by 2a

this formula is applied for

the quadratic equation ax²+bx+c.

Answer 2

Step-by-step explanation:

2x^2+x-4=0

quadratic formula

X =( -b+-√b^2-4ac)/2a

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

x = ( -1+-√1^2-4x2x(-4))/2x2

x= (-1+-√1+32)/4

x =( -1+-√33)/4

x= (-1+√33)/4 x = (-1-√33)/4
