Question

True/False
1. The eq. (x-2)(x+1) = (x-1)(x+3) is a quadratic equation
2. The eq. 2x2-3x+5=0 ha real distinct roots​

Answer 1

Answer:

Given, 2x

2

−3x+5=0

Comparing with the standard quadratic equation is ax

2

+bx+c=0

Here, a=2, b=−3, c=5

Now, D=b

2

−4ac

=9−4×2×5

=−31

Answer 2

Answer:

1) false

(x-2)(x+1)=(x-1)(x+3)

3x-1=0

not quadratic equation

2) false, 2x2-3x+5=0 has no real roots
