√2x + 7x + 5√2=0 to solve this quadratic equation by factorisation
Answers
Correct Question
- √2x² + 7x + 5√2=0 to solve this quadratic equation by factorisation?
Answer
- Zeros are -5/√2 , √2
Given
- √2x² + 7x + 5√2=0
To Calculate
- zeros _?
Explanation
- √2x² + 7x + 5√2=0
➺ √2x²+(5+2)x+5√2=0
➺ √2x²+5x+2x+5√2=0
➺ √2x²+5x+√2×√2x+5√2=0
➺ x(√2x+5)+√2(√2x+5)=0
➺ ( √2x+5)(x+√2) =0
➺√2x+5=0, x+√2=0
➺ x= -5/√2 , x= -√2
Hence
- Zeros are -5/√2 , √2
