7x (x+1.8) = 0

7x (x+1.8) = 0

7x (x+1.8) = 0

Answer those 3

The answer to all of those questions would be x=-1.8

Step-by-step explanation:

7x (x + 1.8) = 0 - Distribute through the Parenthesis -

7x^2 + 12.6x = 0

x (7x + 12.6) = 0

x = 0

7x + 12.6 = 0

7x = - 12.6

x = - 12.6/7

x = - 1.8

so x = 0 or x = - 1.8
