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
