Answer:
Roots for the given polynomial p(x) is x = (2 + √2i) or x = (2 - √2i)
Step-by-step explanation:
Here, the given polynomial is
Now, in <u>COMPLETING THE SQUARE</u> there are various steps.
Step (1): HALF THE COEFFICIENT OF x
Here, the coefficient of x = (4) so , the half of 4 = 4/ 2 = 2
Step(2) :Square it ADD IT ON BOTH SIDES OF EQUATION
The square of 2 is .
Adding it on both sides of the polynomial, we get
Step (3): Use the ALGEBRAIC IDENTITY and make a complete square.
Now, using the identity
or,
Rooting both sides, we get
Solving this, further,we get
x = 2 + √2i , or x = x = 2 - √2i
Hence, roots for the given polynomial p(x) is x = 2 + √2i or x = 2 - √2i
