Answer:
L.H.S
= √2x² + 7x + 5√2.
= √2x² + 2x + 5x + 5√2.
= (√2x² + 2x) + ( 5x + 5√2).
=. ( √2x² + √2 × √2 × x) + ( 5x + 5√2).
=. √2x( x + √2 ) + 5( x + √2 ).
= ( x + √2 ) ( √2x + 5 )
1. x + √2 = 0
x = - √2
2. √2x + 5 = 0
√2x = - 5
x = -5/√2.
Step-by-step explanation:
solve by splitting the middle term.
