In this week I learned how to solve a quadratic equation. A quadratic equation is a equation which the variable in it has a power of 2 or more. In order to solve it, we first have to make one side of the equation’s to zero. For ex. (x+5)(x-7)=0
Now we have a equation, which in it the, the multiplication of two brackets evens to zero. That means one the brackets worths zero. Either x+5=0 or x-7=0. we have to solve these to new equations.
x+5=0 ==> x=-5
x-7=0 ==> x=7
both of these answers are correct and it can be any of them.
