Ifx + 1x 3 find the value ofx2 + 1/x 2
WebTrinomials of the Form x^2 + bx + c. To factor polynomials of the form x 2 + bx + c, begin with two pairs of parentheses with x at the left of each. Next, find two integers whose product is c and whose sum is b and place them at the right of the parentheses. Factor x 2 + 8 x + 12. Factor x 2 – 7 x – 18. Factor x 2 – 6 x + 9.
