The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) Where a, b, c , and a ≠ 0 is called a quadratic equation. The numbers a,b,c are called the coefficients of this equation. A root of the quadratic
Algebra (Linear Equations), In this we are going to learn the solution of linear equations and problems related to it in Algebra. Questions are not directly asked from this topic but it would be very helpful in clearing the concepts. Let’s try to learn what equation is first and its Components. Equation: – A statement
Ratio and Proportion, Let’s first understand what is Ratio and Proportion, when two or more similar quantities are compared, then to represent this comparison, ratios are used. The ratio between x and y can be represented as x:y, where x is called antecedent, and y is called the consequent. x:y or x / y A
To understand the concept of profit and loss, we first have to understand the concept of ‘Percentage’. Percentage, which is clear by name, implies “for every hundred”. This concept is actually developed to make the comparison of fractions easier by equalizing the denominators of all fractions to hundred. e.g. 1. 4/9 can be represented as,
Calculations : Many of us have the same problem in exams, the calculations, tough and lengthy calculations. Sometimes we are stuck in a situation where we face problems like 27 × 64 or 342 and we really have no idea whether to do it manually or leave it because of a shortage of time. So
Simplifications In this section we are going to learn all about VBODMAS rule, what is it, where to use it along with some mind-blowing formulas which will transfer you in a human calculator. E.g. 221 ÷ 13 × √576 + (10)2 = ? We are completely clueless about where to start right now, so let’s
