Answer 1

a) (2x+1)x(x+1)=(x-2)x(2x+5)
2x²+2x+x+1=2x²+5x-4x-10
2x+x+1=5x-4x-10
3x+1=x-10
3x-x=-10-1
2x=-11
x=-11/2
b)(x-1)x(x+1)=x²+2(x-3)
x²-1=x²+2x-6
-1=2x-6
-2x=-6+1
-2x=-5
x=5/2
c)(3+1)²=(3x+2)x(3x-1)
9x²+6x+1=9x²-3x+6x-2
1=-3x-2
3x=-2-1
3x=-3
x=-1
d)(4x-3)=(-2x+0,5)²
4x²-3x=(-2x+1/2)²
4X²-3x=1/4-2x+4x²
-3x=1/4-2x
-3x+2x=1/4
-x=1/4
x=-1/4
nu am timp sa rezolv tot scuze
