In this lesson, look at the definition of the quadratic formula, its standard form, how to plug in your values, and an example of the formula in action. Related to this QuestionWhat are the steps in solving the quadratic equation -5x^2 + 8 = 133? What method can you use to solve a...
It appears when you are solving all kind of geometric problems, such as when you are maximizing an area, given a fixed perimeter, or in numerous word problems. Lots of people wonder if there is any relationship between this quadratic equation formula and the method of completing the square ...
Multiply or divide the same number to both sides of the equation Add or subtract the same number to both sides of the equation In GCSE Maths there are two main types of equations that we need to solve: linear equations and quadratic equations. Methods of solving each are provided below. Ex...
Quadratic simultaneous equations Quadratic simultaneous equations have two or more equations that share variables that are raised to powers up to 2 e.g. x^{2} and y^{2}. Solving quadratic simultaneous equations algebraically by substitution is covered, with examples, in a separate lesson. Step...

The last thing to do is insert x=2 in the original equation to confirm that it is correct. 5(2)+6(2)−22 10+12−22=0 0=0 The final step confirmed that the solution is correct because both sides are equal. Examples of Solving Multi-Step Equations The examples below will show on...
You can ignore this section if you like. But if you're interested in the mathematics of numerical equation solving then read on. There are two ways to solve an equation like: x*x = 2*x + 15 The first is to solve it 'symbolically'. At school you were taught how to rearrange the ...
Solving a quadratic equation by taking the square root involves taking the square root of each side of the equation. Because this equation contains a non-squared x (in 6x), that technique won’t work. Factoring, on the other hand, involves breaking the quadratic equation into two linear e...
Explain the steps involved in solving a simultaneous equation graphically using an example. What is the equation of a line that is parallel to y = -4x + 2 and goes through the point (-4, 9)? Find the equation of the line passing through (-3,4) and parallel ...
