Answer 2

Solution

√2x²+7x+5√2=0

=>√2x²+5x+2x+5√2=0

=>x(√2x+5)+√2(√2+5)=0

=>(√2x+5)(x+√2)=0

therefore..

either..

√2x+5=0

=>x=-5/√2=-5√2/2

or....

X=-√2

explanation

now the coefficient of x²=√2

now the coefficient of x°=5√2

now the coefficient of x¹=7

now..(5√2)×√2=5×2=10

and ....now..

applying..middle term theorm=

(5+2)=7

and...

5×2=10

Hope this helps you......
