- 2What does it mean when a number is to the power of a fraction
- 3What happens when a number is to the power of a negative number
- 4How do you simplify a surdYou change the number in the root into a prime number multiplied by a square number that can be rooted
- 5How do you rationalize the denominator of a fraction with a surd
- 6How do you factorize a quadratic equation
- 7How do you find the x-axis intercepts of a quadratic formulaWhen you have factorized the equation, take the number from each bracket and change its sign (+/-) this will be X
- 8What is the quadratic formula
- 9How do you complete the square
- 10What is meant by domain and rangeThe set of possible inputs for a function is the domain
The possible outputs of a function is the range - 11What do a positive and negative quadratic graphs look like
- 12How do you find the turning point of a graphComplete the square, the number in the bracket is the X coordinate and the number outside is the Y coordinate
- 13What three discriminant equations determine how many real roots an equation has
- 14How do you solve a linear simultaneous equationMake both equations equal to the same thing (e.g. Y) and join the equations. When you have found one value, substitute this into one of the equations to find the other value
- 15How do you solve a quadratic simultaneous equationRearrange the linear equation to equal X or Y; substitute that into the X Y in the quadratic equation to find one of the values, sub that value into the linear equation to find the other value.
