FAQs on Algebra - Formulae Video Lecture - Banking Exams

1. What are some common algebraic formulas?
Ans. Some common algebraic formulas include the quadratic formula, which is used to solve quadratic equations, the slope-intercept form of a linear equation, the distance formula, and the formula for finding the area of a triangle.
2. How do I use the quadratic formula to solve an equation?
Ans. To use the quadratic formula, which is x = (-b ± √(b^2 - 4ac)) / (2a), you need to plug in the values of a, b, and c from the quadratic equation into the formula. Then, simplify the equation by following the order of operations, and solve for the values of x.
3. What is the slope-intercept form of a linear equation?
Ans. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope of the line and b represents the y-intercept, which is the point where the line crosses the y-axis. This form is widely used to graph linear equations.
4. How do I find the distance between two points using the distance formula?
Ans. The distance formula, which is d = √((x2 - x1)^2 + (y2 - y1)^2), allows you to find the distance between two points in a coordinate plane. By substituting the x and y coordinates of the two points into the formula, you can calculate the distance.
5. What is the formula for finding the area of a triangle?
Ans. The formula for finding the area of a triangle is A = (1/2)bh, where A represents the area, b represents the base of the triangle, and h represents the height of the triangle. To find the area, multiply the length of the base by the height and divide the result by 2.
