Answer:
x = - , x =
Step-by-step explanation:
Given
x² - x - = 0 ( add
to both sides )
x² - x =
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( - )x +
=
+
(x - )² = 1 ( take the square root of both sides )
x - = ± 1 ( add
to both sides )
x = ± 1
Thus
x = - 1 = -
x = + 1 =
The equation for this polynomial graphed will be P(x) = a(x + 2)(x + 1)(x – 3)³.
<h3>What is polynomial?</h3>A polynomial expression is an algebraic expression with variables and coefficients.
The graph of the polynomial is given below.
From the graph, the roots of the polynomial will be -2, -1, and 3.
Then the factor of the polynomial will be
(x + 2), (x + 1), and (x – 3)
Then the polynomial will be
P(x) = a(x + 2)(x + 1)(x – 3)³
