Question

find the roots of the following quadratic equations if they exist using the quadratic formula i) 3x2-5x+2=0 ii) x2+4x+5=0

Answer 1

Answer:

A)3x²-5x+2=0

Use the discriminant formula,

b²-4ac=25-24=1>0

So roots exist... And it has two real and unequal roots.....

B)x²+4x+5=0

b²-4ac=16-20=-4<0

So roots doesn't exist...

And the roots are imaginary....
