Use factoring to solve the equation. Use a graphing calculator to check your solution if you wish. $$90 x^{2}-120 x+40=0$$
In Exercises 67 and 68 , use the following information. In every square inch of sailcloth, the warp (lengthwise threads) intersects the weft (crosswise threads) about 9000 times. The density (number of threads per inch) of the weft threads to the warp threads is about 5 to 2. Write an equation that you can solve to find the number of threads per square inch. Let \(x\) represent the number of warp threads.
Use the quadratic formula to solve the equation. $$7 y^{2}-9 y-17=0$$
Solve the equation. \(\left|x+\frac{3}{4}\right|=\frac{9}{4}\)
