Question

check weather the quadratic equation has real roots 6x*2+x-2=0

Answer 1

Answer:

6x^2+x-2 =0

let a=x^2 b=x c=constant variable

therefore,

a=6

b=1

c=2

by using quadratic formula

D = b^2 -4 a c

1^2 -4×6×(-2)

1 - 24×(-2)

1 + 48

D=48

and we know that D>0

therefore it has real roots

thanks for your,,,,
