Question

Find the root of following polynomials : (i)x^2+8 (ii)4x

Answer 1

Answer: i) x =±√-8 or ± i√8

             ii) x =0

Step-by-step explanation:

To find root equate the polynomials to 0.

i) x² +8 =0

x² = -8

x =±√-8 or ± i√8

ii) 4x =0

x=0

Answer 2

Answer:

1. x²+ 8 = 0

x²+ (√8)² = 0 {a²+b²= (a+b) (a - b)}

(x + √8 ) = 0 ( x - √8)= 0

x = -√8 x = √8

x = -√4(2) x = √4(2)

x = -2√2 x = 2√2

2. 4x = 0

x = 0/4

x = 0
