Question

solve by factorisation meathod √2 x²+7x+5√2=0​

Answer 1

Step-by-step explanation:

Given,

2x2+7x+52=0

or, 2x2+2x+5x+52=0

or, x2(x+2)+5(x+2)=0

or, (x2+5)(x+2)=0

⇒x=−25,−2.(ans)

Answer 2

√2 x^2+7x+ 5√2 = 0

Or, √2x^2+2x+ 5x+ 5√2= 0

Or, √2x(x+√2)+5(x+√2) = 0

Or, ( x+√2) (√2x+5) = 0

x = -√2 ,-5/√2

So, the answer is (-√2 ) ,( -5/√2 )
