Examples
(1,5)(1,5)
Step 1
x=1x=1 and x=5x=5 are the two real distinct solutions for the quadratic equation, which means that x-1x−1 and x-5x−5 are the factors of the quadratic equation.
(x-1)(x-5)=0(x−1)(x−5)=0
Step 2
Step 2.1
Apply the distributive property.
x(x-5)-1(x-5)=0x(x−5)−1(x−5)=0
Step 2.2
Apply the distributive property.
x⋅x+x⋅-5-1(x-5)=0x⋅x+x⋅−5−1(x−5)=0
Step 2.3
Apply the distributive property.
x⋅x+x⋅-5-1x-1⋅-5=0x⋅x+x⋅−5−1x−1⋅−5=0
x⋅x+x⋅-5-1x-1⋅-5=0x⋅x+x⋅−5−1x−1⋅−5=0
Step 3
Step 3.1
Simplify each term.
Step 3.1.1
Multiply xx by xx.
x2+x⋅-5-1x-1⋅-5=0x2+x⋅−5−1x−1⋅−5=0
Step 3.1.2
Move -5−5 to the left of xx.
x2-5⋅x-1x-1⋅-5=0x2−5⋅x−1x−1⋅−5=0
Step 3.1.3
Rewrite -1x−1x as -x−x.
x2-5x-x-1⋅-5=0x2−5x−x−1⋅−5=0
Step 3.1.4
Multiply -1−1 by -5−5.
x2-5x-x+5=0x2−5x−x+5=0
x2-5x-x+5=0x2−5x−x+5=0
Step 3.2
Subtract x from -5x.
x2-6x+5=0
x2-6x+5=0
Step 4
The standard quadratic equation using the given set of solutions {1,5} is y=x2-6x+5.
y=x2-6x+5
