Question

What is the factored form of the polynomial? (z2 10z + 25)
A. (z − 5)(z − 5)
B. (z + 5)(z + 5)
C. (z − 2)(z + 5)
D. (z + 2)(z − 5)

Answer 1

Solution-

As the question is not complete so contemplating all the possible scenarios,

1st - z² + 10z + 25

2nd - z² - 10z + 25

For,

$z^2 + 10z + 25 = (z)^2+2.z.5+(5)^2 = (z+5)^2=(z+5)(z+5)$

And for,

$z^2 - 10z + 25 = (z)^2-2.z.5+(5)^2 = (z-5)^2=(z-5)(z-5)$

So, the factored form of the polynomials are,

$(z+5)(z+5) \ and \ (z-5)(z-5)$

Answer 2

The factors of the equation  z² - 10z + 25 are (z − 5)(z − 5).

Given Equation;

z² - 10z + 25

What are the factors?

Splitting the middle term Using formula Using Quadratic formula Using algebraic identities.

The factors of the equation are;

z² - 10z + 25

z² -5z -5z  + 25

z(z − 5) - 5(z − 5)

(z − 5)(z − 5)

Hence, the factors of the equation z² - 10z + 25 are (z − 5)(z − 5).
