Question

If b2-4ac=0, then the curve of the Quadratic Equation touches the x-axis at
a) One point b) Two points c) No points d) Non​

Answer 1

Answer:

option b two points what's the answer

Answer 2

HEYA!!

The discriminant of quadratic equation.

$a {x}^{2} + bx + c = 0 \: is \: {b}^{2} - 4ac$

which is given zero in the equation so both roots will be equal and real

then the parabola will touch x- axis and since parabola is a>0 parabola will be upward.

Hence option A is correct
