The first step (as they covered extensively in class) for solving a quadratic is to get "(quadratic) = 0". So your first step should be to move the 21k and the 49 to the left-hand side.
Then apply whatever methods you learned (the Quadratic Formula, completing the square, etc) to solving the equation.
Um... "Is this even close" to what...? It's not even related to the exercise, other than having the same variable. And "140k" obviously isn't a solution to the equation! :shock:
Please reply with clarification, showing your steps and reasoning, and using complete sentences so we can figure out what you mean. Thank you!
