Question

Determine the nature of the roots of the following quadratic equations from their discriminant
1. 3y²+9y+4=0
2. 2x²+5√3+16=0
3. 4x²+12x+9=0
4. m²+√2m+1=0
5.x²-1/2x+1/16=0
​

Answer 1

Answer:

Given equation is, 3y

2

+9y+4=0

We know,D=b

2

−4ac

a=3,b=9,c=4

D=(9)

2

−4(3)(4)

∴D=33

Since, D>0 the roots are real and unequal.
