Answer:

p[\sqrt{15},); p\geq \sqrt{15}

Step-by-step explanation:

Given Quadratic equation:

5x^{2} -2px+3 = 0

Previous Knowledge:

We know that for a quadratic equation, of the form ax^{2} +bx+c = 0, has real roots when b^{2} -4ac\geq 0

To Find:

Values of p for which the given equation has real roots

Solution:

The equation must have real roots

b^{2} -4ac \geq 0                                                         (Previous Knowledge)

(-2p)^{2} -4(5)(3) \geq 0

4p^{2} -60 \geq 0

Adding 60 to both sides

4p^{2}  \geq 60

Dividing by 4 on both sides

p^{2} \geq 15

Rooting both sides

p\geq \sqrt{15}

In terms of Sets that means

p[\sqrt{15},)
