Question 98447: Most quadratic eqautions Ive come across so far have given the problem as something equals 0 format. This one below is the first Ive seen in this format so its got me scratching my head.
Use the quadratic equation to solve: 6n^2= -8n-1
Give the answer in decimal form.
This neither has the equals 0 as a start point or ask me what to solve for. It just says solve. Help please.
Thank you.
