Complete the square on each of the following.
x2 -16x
Solution
Here's the number which we'll insert to the equation.
( -16 /2 ) = (-8)2 = 64
Notice that we put the minus sign here although it will always drop out after we square things. The cause for this will be clear in a second. Now let's complete the square.
x2 -16 x + 64 =( x - 8)2
Now, it is a quadratic hopefully that you can factor fairly rapidly. Though notice that this will always factor as x plus the blue number we calculated above i.e. in the parenthesis (in our case i.e. -8). This is the cause for leaving the minus sign. It ensures that we don't commit any mistakes in the factoring procedure.
2x+5=-8
Solve a quadratic equation through completing the square Now it's time to see how we employ completing the square to solve out a quadratic equation. The procedure is best seen
The sum of the ages of Dorothy and Dona is 41. In 5 years, Dorothy will be twice as old as Dona. Find their age 3 years ago.
graph the following and find the point of intersection 2x+y=-4 y+2x=3
50 units for 580 dollars a month, rent increase 625.00 now only 47 units occupied
1/1+x+1/y+1/1+z+1/x+1/1+y+1/z=1
Here we'll be doing is solving equations which have more than one variable in them. The procedure that we'll be going through here is very alike to solving linear equations that i
Solve 2 x 10 - x 5 - 4 = 0 . Solution We can reduce this to quadratic in form using the substitution, u = x 5 u 2 = x 10 By using this substitution the equa
how do you solve a literal equation?
Also, as x obtain very large, both positive & negative, the graph approaches the line specified by y = 0 . This line is called a horizontal asymptote. Following are the genera
