X(2-√2)=- 1(2-√2)

X= 1 Question 2: Solve B 2-4ac/2A under the root sign of -B with the quadratic equation formula of the Second Hospital.

Question 3: 3x(x- 1)=2-2x.

3x(x- 1)=-2(x- 1)3x(x- 1)+2(x- 1)= 0

(3x+2)(x- 1)=0

So x= 1 or -3/2 Question 4: (m+2)(2m-5)=- 10.

2m^2-5m+4m- 10

=- 10

2m^2-m=0

m(2m- 1)=0

And because m≠0

So m= 1/2.
