You have to write each expression in two other ways

Which polynomial function has x intercepts -1, 0, and 2 and passes through the point (1, -6)

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
