If a polynomial has one root in the form a+√b , it has a second root in the form of a_√b
gulaghasi [49]
When roots of polynomials occur in radical form, they occur as two conjugates.
That is,
The conjugate of (a + √b) is (a - √b) and vice versa.
To show that the given conjugates come from a polynomial, we should create the polynomial from the given factors.

The first factor is x - (a + √b).
The second factor is x - (a - √b).

The polynomial is
f(x) = [x - (a + √b)]*[x - (a - √b)]
      = x² - x(a - √b) - x(a + √b) + (a + √b)(a - √b)
      = x² - 2ax + x√b - x√b + a² - b
      = x² - 2ax + a² - b

This is a quadratic polynomial, as expected.

If you solve the quadratic equation x² - 2ax + a² - b = 0 with the quadratic formula, it should yield the pair of conjugate radical roots.
x = (1/2) [ 2a +/- √(4a² - 4(a² - b)]
   = a +/- (1/2)*√(4b)
   = a +/- √b
x = a + √b, or x = a - √b, as expected.

11. The perimeter of a rectangular garden is 96 ft. The length is five times the width. Find
asambeis [7]

Answer:

Length =40 ft.

width. = 8 ft.

Step-by-step explanation:

If The length is five times the width , then

width = w

length = 5w

Perimeter of Rectangle = 2( l+b)

2(5w+w)= 96

2( 6w) = 96

12 w= 96

w = 96/12

w= 8ft.

length = 5(8)

= 40 ft

slavikrds [6]

Answer:

126 = n × (n - 5)

Step-by-step explanation:

If Nikki's age is <em>n </em>and she is 5 years older than Jamie, then Jamie is 5 years younger than Nikki's <em>n </em>number of years.
