Given :
- P(x) = x² - 3√5x + 10 = 0
To Find :
- Value of x
Solution :
→ x² - 3√5x + 10 = 0
→ x² - √5x - 2√5x + 10 = 0
→ ( x²- √5x ) + ( - 2√5x + 10 ) = 0
→ x ( x - √5 ) -2√5 ( x - √5 ) = 0
→ ( x - √5 ) ( x - 2√5 ) = 0
When x - √5 = 0
→ x = √5
When x - 2√5 = 0
→ x = 2√5

YOUR QUESTION :
solve quadratic equation : x^2 − 3√5 + 10 = 0
YOUR ANSWER :
Given :
- P(x) = x^2 − 3√5 + 10 = 0.
To find :
- Value of x.
Solution :
x² - 3√5x + 10 = 0
=> x² - √5x - 2√5x + 10 = 0
=> ( x² - √5x ) ( - 2√5x + 10 ) = 0
=> x ( x - √5 ) - 2√5 ( x - √5 ) = 0
=> ( x - √5 ) ( x - 2√5 )
When x - √5 = 0
=> x = √5.
When x - 2√5 = 0
=> x = 2√5.
