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
