Q= -12
Explain:
Basically we divide both sides by 0.75
Then expand 108 over 0.75 multiplying both by 100 so q cubed= 10800 over 75 when we divide 10800 with 75 we get q cubed=144 then we subtract 144 from each side consider q cubed - 144 rewrite it as q cubed minus 12 cubed the squares can be factored by a cubed and b cubed = ( a - b )(a+b)
So then it’s (q -12) (q+12) = 0 to find solution you gotta solve q - 12 = 0 and q+ 12=0
