If you meant 2x+3=4x²x=(1±√(13))/4x1≈1.151387818866x2≈-0.651387818866
4X1 = four times one. 2X0.1 = two times one tenth.
2 * - 2 = - 4 ---------------- 1 * - 4 = - 4 ---------------- - 1 * 4 = - 4 ---------------- Some of the simple ones without fractions.

Well, 1.25 is basicly 1 1/4, right? So you multiply the denominator and the whole number together (4x1) and add the numerator (4x1+1). The answer is 5/4.
4X1 = four times one. 2X0.1 = two times one tenth.
2 * - 2 = - 4 ---------------- 1 * - 4 = - 4 ---------------- - 1 * 4 = - 4 ---------------- Some of the simple ones without fractions.
