Quadratics Formula. The formula for a quadratic equation is used to find the roots of the equation. Since quadratics have a degree equal to two, therefore there will be two solutions for the equation. Suppose ax² + bx + c = 0 is the quadratic equation, then the formula to find the roots of this equation will be: x = [-b±√ (b2-4ac)]/2a.Thus, we can summarize some properties of the correlation coefficient as follows. ρ(aX + b, cY + d) = ρ(X, Y) for a, c > 0. - If ρ(X, Y) = 0, we say that X and Y are uncorrelated. - If ρ(X, Y) > 0, we say that X and Y are positively correlated. - If ρ(X, Y) < 0, we say that X and Y are negatively correlated.Với Các bài toán về các tập hợp số và cách giải sẽ giúp học sinh nắm vững lý thuyết, biết cách và phương pháp giải các dạng bài tập từ đó có kế hoạch ôn tập hiệu quả để đạt kết quả cao trong các bài thi môn Toán 10. 1.
