Consider 12x = 60. To find x, we intuitively try to find that 12 times what number is 60. We find that 5 is the required number. Solving equations by trial and error method is not always easy.
We need to isolate the variable x for solving an equation. Let us use the separation of variables method or the balancing method to solve it. Consider an equation 2x + 3 = 17. We first eliminate 3 in the first step. To keep the balance while solving the equation, we subtract 3 from either side of the equation. Thus 2x + 3 - 3 = 17 - 3 We have 2x = ...
While solving an equation, we change the sides of the numbers. This process is called transposing. While transposing a number, we change its sign or reverse the operation. Consider 5y + 2 = 22. We need to find y, so isolate it. Hence we transpose the number 2 to the other side. The equation becomes, 5y = 22-2 5y = 20 Now taking 5 to the other side,...
Solving an equation of quadratic type by completing the squares method is quite easy as we apply our knowledge of algebraic identity: (a+b)2 1. Write the equation in the standard form ax2+ bx + c = 0. 2. Divide both the sides of the equation by a. 3. Move the constantterm to the other side 4. Add the squareof one-half of the coefficient of x on bot...
Solving an equation of quadratic type using the factorization method, follow the steps discussed here. Write the given equation in the standard form and by splitting the middle terms, factorize the equation. Rewrite the equation obtained as a product of two linear factors. Equate each linear factor to zero and solve for x. Consider 2x2 + 19x + 30 =...
Solving an equation of quadratic type using the formula x = [-b ± √[(b2 -4ac)]/2a helps us find the roots of the quadratic equation ax2+ bx + c = 0. Plugging in the values of a, b, and c in the formula, we arrive at the solution. Consider the example: 9x2 -12 x + 4 = 0 a= 9, b = -12 and c = 4 x = [-b ± √[(b2 -4ac)]/2a = [12 ± √[((-12)2 -4×9×4)] / (...
Introduction to Derivatives. It is all about slope! Let us Find a Derivative! To find the derivative of a function y = f (x) we use the slope formula: Slope = Change in Y Change in X = Δy Δx. And (from the diagram) we see that: Now follow these steps: Fill in this slope formula: Δy Δx = f (x+Δx) − f (x) Δx. Simplify it as best we can.
