Quadratic polynomial can be factored using the transformation
where x1 and x2 are the solutions of the quadratic equation
All equations of the form ax2+bx+c=0 can be solved using the quadratic formula: −b±b2−4ac2a. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
Multiply -4 times -1
Multiply 4 times -1100
Add 14400 to -4400
Take the square root of 10000
Multiply 2 times -1
Now solve the equation x=−120±100−2 when ± is plus
Add -120 to 100
Divide -20 by -2
Now solve the equation x=−120±100−2 when ± is minus
Subtract 100 from -120
Divide -220 by -2
Factro the original expression using ax2+bx+c=a(x−x1)(x−x2). Substitute 10 for x1 and 110 for x2
