The second method of solving quadratics is square root property,
If p2 = d then p =±d
There is a (potentially) new symbol that we have to define first in case you haven't seen it still. The symbol "± " is named as : "plus or minus" & i.e. exactly what this tells us. This symbol is shorthand which tells us that we actually have two numbers here. One is p =√d and the other is p = √- d .
It is a fairly simple property to use, however it can just used on a small portion of the equations which we're ever likely to encounter. Let's see some examples of this property.
The sum of digits of a number is 9 If the digits of the number are reversed the number increases by 45 What is the original number?
k^(2-) k-30
Name the property illustrated by the following? x + (-x)=0
2x+y/x+3y=-1/7and 7x+36y=47/3 hence find p if xy=p=x/y
I do not know how to do this
All parabolas are vaguely "U" shaped & they will contain a highest or lowest point which is called the vertex. Parabolas might open up or down and may or may not contain x-inte
