- In Exercises 11–12, solve each quadratic equation using the quadratic formula. Express solutions in standard form. 12. 2x? - 6x + 5 = 0 11. x? - 2r + 4 = 0arrow_forwardExercises 135–137 will help you prepare for the material covered in the next section. In each exercise, use properties of exponents to simplify the expression. Be sure that no negative exponents appear in your simplified expression. (If you have forgotten how to simplify an exponential expression, see the box on page 77.) 135. (2°r)(24x-6) 32x2 136. 16x 137. (x-2y³)*arrow_forwardExercises 86–88 will help you prepare for the material covered in the next section. If –9 is substituted for x in the equation 4x – 3 = 5x + 6, is the resulting statement true or false? Simplify: 13 – 3(x + 2). Зх + Simplify: 10(**1).arrow_forward
- Please simplify completely. In #1–4, list the necessary restrictions on the variable; if none, write “none”.arrow_forwardUse the graphs of the linear functions to solve Exercises 89–90. x + 3y = 12 x - 3y = -6 x - y = 4 x - 3y = 6 89. Write the linear system whose solution set is {(6, 2)}. Express each equation in the system in slope-intercept form.arrow_forwardVerify that each equation is an identity. See Examples 1–5.arrow_forward
