(1). If f(x)=x²-2x, find f(-1) = (2). By canceling rỉ -5x+6 x-2 f(x) = (3). Let f(x)=3x². (4).. sin 30° = = x-2, simplify the function -x, so f(-)= r= X (1). x² - 7x+6 (5). The solution of the inequality |x-1|<1 is 2. Factorize the following polynomials. (6points in total) tan 30º = (1). If f(x)=x²-2x, find f(-1) = (2). By canceling rỉ -5x+6 x-2 f(x) = (3).
