Quadratic equations contain the term x2 and they can normally be written in the format of:ax2 + bx + c = 0. You can solve these equations by using a technique called factorisation. F...
To factorize this you need to find two numbers that have a sum of -1 and a product of -12. Start y finding the pairs of numbers the times to make -12; (-1,12), (-2,6), (-3,4), (1,-12), (3,-4), (2,-6). Nex...
The three trigonometric functions sine, cosine, and tangent are derived from looking at the ratios of side lengths in a right-angled triangle. (Triangle drawn and side lengths annotated H=hypotenuse, A=ad...
Firstly I check that the equation is of the form ax2 +bx+c=0 , here it is in such form as a=3 b=-1 c=-10. Because it is a quadratic equation, it can be factorised into 2 brackets. In each brack...
Quadratic equations have a variable usually the letter x (but it could be any letter or symbol in theory).The value of x is unknown but you can work it out after following a few simple steps. Here is an e...
