The answer would be p= -2

To check it:
-2(5(-2) - 3) = 26
-2(-10-3) = 26

98 POINTS!!!<br><br>Write a polynomial function in standard form given the zeros<br><br><br>±√5 , 7
Neporo4naja [7]

Answer:

Step-by-step explanation:

Knowing the three zeros of the equation, we can set it up as follows:

(x - \sqrt{5})(x + \sqrt{5})(x - 7)

Multipying the first two expressions together gives us the following:

(x^{2} - 5)(x - 7)

Multiplying the two expressions together gives us the following:

x^{3} - 7x^{2} - 5x + 35
