Question

X+4×-2²-(3/x).=
5x=
5×+2=
x¹+x+1²
..........??????​

Answer 1

1.)

$x + 4 x - 2 (\frac{3}{x} )\\\\ x+ 4x -2^{2} - \frac{3}{x} \\\\5x - 2^{2} - \frac{3}{x} \\\\\\2^{2} = 4\\5x - 4 - \frac{3}{x}$

2.)

$\frac{x}{5} \\\\5x \\\\m = 5$

3.)

5×+2  

X intersecta  ( -2/5 , 0 )   Y intersecta  (0,2)

x-2

 5

m= 5

4.)

$x^{1} + x + 1^{2} \\\\x^{1} + x + 1\\\\x + x = 1\\\\ = 2x + 1$
