In Problems 39–42, write each expression in the form ax p + bx q or ax p + bx q + cx r , where a, b, and c are real numbers and p, q, and r are integers. For example, 2 x 4 − 3 x 2 + 1 2 x 3 = 2 x 4 2 x 3 − 3 x 2 2 x 3 + 1 2 x 3 = x − 3 2 x − 1 + 1 2 x − 3 42. 2 x 3 − 3 x 2 + x 2 x 2
In Problems 39–42, write each expression in the form ax p + bx q or ax p + bx q + cx r , where a, b, and c are real numbers and p, q, and r are integers. For example, 2 x 4 − 3 x 2 + 1 2 x 3 = 2 x 4 2 x 3 − 3 x 2 2 x 3 + 1 2 x 3 = x − 3 2 x − 1 + 1 2 x − 3 42. 2 x 3 − 3 x 2 + x 2 x 2
