ウェブ2023年9月5日 · Using the Quadratic Formula, we get x = 1 ± √3. Graphing f(x) = 1 + 2ln ( x + 1) ln ( 4) and g(x) = 2ln ( x) ln ( 2), we see the graphs intersect only at x = 1 + √3 ≈ 2.732. The solution x = 1 − √3 < 0, which means if substituted into the original equation, the term 2log2(1 − √3) is undefined.
