Simplifying 10x2 = y(21 + y) 10x2 = (21 * y + y * y) 10x2 = (21y + y2) Solving 10x2 = 21y + y2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '10'. x2 = 2.1y + 0.1y2 Simplifying x2 = 2.1y + 0.1y2 Reorder the terms: x2 + -2.1y + -0.1y2 = 2.1y + -2.1y + 0.1y2 + -0.1y2 Combine like terms: 2.1y + -2.1y = 0.0 x2 + -2.1y + -0.1y2 = 0.0 + 0.1y2 + -0.1y2 x2 + -2.1y + -0.1y2 = 0.1y2 + -0.1y2 Combine like terms: 0.1y2 + -0.1y2 = 0.0 x2 + -2.1y + -0.1y2 = 0.0 The solution to this equation could not be determined.
