Question

The value of p for which the quadratic equation x x - 4 + p is equal to zero has real root is

Answer 1

Answer:

$4$

Step-by-step explanation:

For any quadratic equations to have real roots, it should have discriminant to be 0

D=

${b}^{2} - 4ac = 0$

insert the values of quadratic equations given

$x { }^{2} - 4 + p$

16-4p=0

p=4.

that's the a answer.

I think it is clear now.

so, please mark it as a brainliest.
