Answer:
Step-by-step explanation:
7) root 2 x square -3x- 2root 2=0 is in the form-
ax square+bx+c=0
multiply root 2x square and 2root2 we get 4 (a*c)
root 2 x square -4x+x- 2root 2=0
√ 2 x(x-2√2) + 1(x-2√2)=0
(√2x+1) (x-2√2)=0
x=2√2 and -1/√2
roots of the above equation are 2√2 and -1/√2

do the first one please
=>x∗(x−2√2)−2√2(x−2√2)−2=0
=>(x−2v2) whole square−√2 square=0
=>(x−2√2) whole square=√2 square
=>(x−2√2)=±√2
