Question

3. The quadratic equation 2x-3x+5=0 has ...........real roots.
​

Answer 1

Answer:

Here the quadratic equation is 2x

2 −3x+5=0

Comparing it with ax ^2 +bx+c=0, we get

a=2,b=−3,c=5

Therefore, discriminant, D=b −4ac

2 −4×2×5

=9−40

=−31

Here, D<0

Therefore the equation has no real roots.

Answer 2

Answer:

ur question is wrong

2x^2-3x+5=0

so the ans is

2x^2-3x+5=0

by splitting,we get

2x^2-5x+2x+5=0

x(2x-5)-1(2x-5)

(x-1)(2x-5)

x-1=0,2x-5=0

x=1,2x=5

x=1,x=5/2

x=1,5/2

it has two roots(this is factorisation method or generalization method)
