Explicación paso a paso:
Simplifying
x2 + -6x + 10 = 2x + 3
Reorder the terms:
10 + -6x + x2 = 2x + 3
Reorder the terms:
10 + -6x + x2 = 3 + 2x
Solving
10 + -6x + x2 = 3 + 2x
Solving for variable 'x'.
Reorder the terms:
10 + -3 + -6x + -2x + x2 = 3 + 2x + -3 + -2x
Combine like terms: 10 + -3 = 7
7 + -6x + -2x + x2 = 3 + 2x + -3 + -2x
Combine like terms: -6x + -2x = -8x
7 + -8x + x2 = 3 + 2x + -3 + -2x
Reorder the terms:
7 + -8x + x2 = 3 + -3 + 2x + -2x
Combine like terms: 3 + -3 = 0
7 + -8x + x2 = 0 + 2x + -2x
7 + -8x + x2 = 2x + -2x
Combine like terms: 2x + -2x = 0
7 + -8x + x2 = 0
Factor a trinomial.
(1 + -1x)(7 + -1x) = 0
Subproblem 1
Set the factor '(1 + -1x)' equal to zero and attempt to solve:
Simplifying
1 + -1x = 0
Solving
1 + -1x = 0
1 + -1 + -1x = 0 + -1
Combine like terms: 1 + -1 = 0
0 + -1x = 0 + -1
-1x = 0 + -1
Combine like terms: 0 + -1 = -1
-1x = -1
Divide each side by '-1'.
x = 1
Simplifying
x = 1
Subproblem 2
Set the factor '(7 + -1x)' equal to zero and attempt to solve:
Simplifying
7 + -1x = 0
Solving
7 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + -1x = 0 + -7
Combine like terms: 7 + -7 = 0
0 + -1x = 0 + -7
-1x = 0 + -7
Combine like terms: 0 + -7 = -7
-1x = -7
Divide each side by '-1'.
x = 7
Simplifying
x = 7
