Question

98 POINTS!!!Write a polynomial function in standard form given the zeros±√5 , 7

Answer 1

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:

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

Answer 2

Set up an expression.

= [(x + √5)(x - √5)](x - 7)

~Multiply

= (x² - 5)(x - 7)

~Multiply

= x³ - 7x² - 5x + 35

Best of Luck!
