Using the quadratic equation formula: x = -5-/+ the square root of 7
The number of solutions an equation has depends on the nature of the equation. A linear equation typically has one solution, a quadratic equation can have two solutions, and a cubic equation can have three solutions. However, equations can also have no solution or an infinite number of solutions depending on the specific values and relationships within the equation. It is important to analyze the equation and its characteristics to determine the number of solutions accurately.
x^2-3x-28=0...................
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
