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

$\longrightarrow$ √2x²+(5+2)x+5√2=0

$\longrightarrow$√2x²+5x+2x+5√2=0

$\longrightarrow$√2x²+5x+√2×√2x+5√2=0

$\longrightarrow$(√2x+5)+√2(√2x+5)=0

$\longrightarrow$( √2x+5)(x+√2) =0

$\longrightarrow$√2x+5=0, x+√2=0

$\longrightarrow$ x= -5/√2 , x= -√2

Hence,

Zeros are -5/√2 , √2
