Question

(45x) = (25x) (57+x)

Answer 1

Solution is X1 = -276/5, x2 = 0

Answer 2

x = 0; x =
`(-276)/(5)`

Explanation:

45x = 25x(57 + x)

45x = 1425x + 25x²

25x² + 1425x - 45x = 0

25x² + 1380x = 0

5x(5x + 276) = 0

`\left \{ {{5x=0} \atop {5x + 276=0}} \right.`

`\left \{ {{x=0} \atop {x=(-276)/(5) }} \right.`
