25x(-2=-100 solve the full answer
Answers
Answer:
25x + -1x2 = 100
Solving
25x + -1x2 = 100
Solving for variable 'x'.
Reorder the terms:
-100 + 25x + -1x2 = 100 + -100
Combine like terms: 100 + -100 = 0
-100 + 25x + -1x2 = 0
Factor a trinomial.
(-20 + x)(5 + -1x) = 0
Subproblem 1
Set the factor '(-20 + x)' equal to zero and attempt to solve:
Simplifying
-20 + x = 0
Solving
-20 + x = 0
Move all terms containing x to the left, all other terms to the right.
Add '20' to each side of the equation.
-20 + 20 + x = 0 + 20
Combine like terms: -20 + 20 = 0
0 + x = 0 + 20
x = 0 + 20
Combine like terms: 0 + 20 = 20
x = 20
Simplifying
x = 20
Subproblem 2
Set the factor '(5 + -1x)' equal to zero and attempt to solve:
Simplifying
5 + -1x = 0
Solving
5 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + -1x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + -1x = 0 + -5
-1x = 0 + -5
Combine like terms: 0 + -5 = -5
-1x = -5
Divide each side by '-1'.
x = 5
Simplifying
x = 5
Solution
x = {20, 5}
