What two values of x are roots of the polynomial below
Anarel [89]
Both A and B will be answers to the solution. 

Since you already have the equation set and equal to 0, you can find the roots by first getting your a, b, and c values for the quadratic equation. 

a = 1 (number attached to the x^2)
b = -3 (number attached to the x)
c = 5 (number not attached to a variable)

Then we can use these values in the quadratic equation. 

\frac{-b +/-  \sqrt{ b^{2} -4ac } }{2a}

\frac{3 +/- \sqrt{ -3^{2} -4(1)(5) } }{2(1)}

\frac{3 +/- \sqrt{-11 } }{2}

(x-1)²-25=0<br> Factor by using the difference between two squares
Ronch [10]

Answer:

see explanation

Step-by-step explanation:

A difference of 2 squares factors in general as

a² - b² = (a - b)(a + b)

(x - 1)² - 25 ← is a difference of squares

with a = x - 1 and b = 5, thus

(x - 1)² - 25

=(x - 1 - 5)(x - 1 + 5) = (x - 6)(x + 4), then

(x - 6)(x + 4) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 4 = 0 ⇒ x = - 4

Solutions are x = - 4, x = 6
