rezolvați doar c, d, e și f! Dau multe puncte și dau coroana. ​

Answer 1

c) 2x(√3+√2)-√2(3+2x)= √3(x+√2)

2√3x+2√2x-3√2-2√2x= √3x+√6

2√3x-3√2= √3x+√6

2√3x-√3x= √6+3√2

√3x= √6+3√2

x= √2+ 3√2/√3

x= √2+ √6

d) 3x(√3+√5)-x(3√5-2√3)= 2√3(x+3√5)

3√3x+3√5x-3√5x+2√3x= 2√3x+6√15

3√3x+2√3x= 2√3x+6√15

3√3x= 6√15

x= 2√5

e) 2√3(x+√6)-x(√3+1)= 7√2-x

2√3x+2√18-√3x-x= 7√2-x

2√3x+6√2-√3x= 7√2

√3x+6√2= 7√2

√3x= 7√2-6√2

√3x= √2

x= √2/√3

x= √6/3

f) 5√2(x-√8)-2(x-5)= x(3√2-2)

5√2(x-2√2)-2x+10= 3√2x-2x

5√2x-20+10= 3√2x

5√2x-10= 3√2x

5√2x-3√2x= 10

2√2x= 10

x= 10/2√2

x= 5/√2

x= 5√2/2

,,/"= supra/pe

ex: a/b => a supra b, a pe b
