Square the two cube roots to get the first and third term of the second factor. Multiply the two cube roots together to get the second term of the second factor. In the above example, the first and third terms are x^2 and 9, respectively (3 squared is 9). The middle term is 3x....
In the binomials section he tries to explain how to factorise 2x2-4x, to get to the answer 2x(x-2). He did this by expanding the binomial function. The common factor in the equation 2x2-4x is 2x, this is because there is a 2x in 2x2 obviously but a 2x inside -4x also. there...
During math class in grade school, we were taught how tofactor equations. It is possible you may have forgotten or need a refresher. You may need to factorise if you are going to college or study for a preparation exam. Follow these steps on how to factorise. To factor numbers, practice...
Use the equation x²-10x+24 as an example and factorise it as the product of two binomials. Fill in the missing terms of the binomials with the two integers a and b whose product is +24, the constant term of x²-10x+24, and whose sum is -10, the coefficient of the x term....
The easiest way to understand this concept is to use an example, for instance, the equations y = 2x and y = 3x + 1. Independently, these two equations each have a range of values, the y value changing depending on which x value you plug into the equation. Together, however, these tw...
What is 75 squared? How does someone calculate the percentage of something? How do you change a fraction into a percent? How do you simplify the equation f+4(f-2) Factorise by grouping : 2x^3-3x^2+6x+4 How could one share $96 so that A has twice as much as B?
a universal constant that shows up naturally in calculations with round objects. The second variable, r, stands for radius. Radius is the measurement from the center of the circle to the edge. To find the area of the circle, the radius will be squared before being multiplied by π...
The expression x^y means x to the y power, for example: 2^3 equals 2 times 2 times 2, which yields 8. An example of simplifying monomials using the power of a power rule might be: [3x^3 y^2]^2 = 9x^6 y^4. If x = 2 and y = 3, on the left side of the equation, yo...

Utilize the first outer inner last (FOIL) method to multiply the first two equations. Further explanation of the FOIL method is found in the references section. Example: (3x+2)*(x+3) Becomes: (3x^2+11x+6) Multiply the last given equation (which you did not foil), by the new equatio...
