Question

✓2x^2+7x+5✓2 and X=-✓2 find the value of X​

Answer 1

Answer:

Given,

2 x2 +7x+5 2=0

or,

2 x2+2x+5x+5 2=0

or,

x 2 (x+ 2 )+5(x+ 2 )=0

or,

(x 2 +5)(x+ 2 )=0

⇒x= --25 ,− 2

.

These are the required roots.

Answer 2

Answer:

Given,

√2x^+7x+5 2=0

or, √2x^+2x+5x+5√2=0

or, x√2(x+ √2 )+5(x+√2)=0

or, (x√2+5)(x+√2 )=0

or, x=−5/√2 ,

(x= −√2)
