Question

2x^2 +3 (root5)x +5..............

Answer 1

Correction : 2x² + 3√5x + 5

Let Polynomial be f(x) = 2x² + 3√5x + 5

Step 1 , Solve Polynomial.

2x² + 3√5x + 5

☞ 2x² + 2√5x + √5x + 5

☞ 2x(x+√5) + √5(x+√5)

☞ (2x+√5) (x+√5)

So, Zeros of Polynomial!

f(x)= 2x+√5. 0r x + √5 = 0

☞ 2x = -√5. 0r x = -√5

☞ x = -√5/2

Therefore, Zeros of Polynomial are -√5/2 and -√5.
