WebHidden Quadratic Equations (C) Sometimes quadratic equations come in disguise like 𝑢4−3𝑢2+4=0 𝑜𝑟 𝑢+2 𝑢2+1 =4 or even 𝑒𝑥−𝑒−𝑥 2 =4 (2) which can be seen to be a quadratic equation in ex by multiplying through by 2ex. Hidden quadratic equations such as (2) are most easily solved by substitution.

10.5 Solving Quadratic Equations Using Substitution

WebUsing a calculator for approximation, x ≈ 12.770. To solve an equation involving logarithms, use the properties of logarithms to write the equation in the form log bM = N and then change this to exponential form, M = b N . Example 2. Solve the following equations. log 4 (3 x – 2) = 2. log 3 x + log 3 ( x – 6) = 3. Web1. I paid $250,000 for my lake home 5 years ago.
