(x + 3)(x + -3) = 16 + -1(2x2)
Reorder the terms:
(3 + x)(x + -3) = 16 + -1(2x2)
Reorder the terms:
(3 + x)(-3 + x) = 16 + -1(2x2)
Multiply (3 + x) * (-3 + x)
(3(-3 + x) + x(-3 + x)) = 16 + -1(2x2)
((-3 * 3 + x * 3) + x(-3 + x)) = 16 + -1(2x2)
((-9 + 3x) + x(-3 + x)) = 16 + -1(2x2)
(-9 + 3x + (-3 * x + x * x)) = 16 + -1(2x2)
(-9 + 3x + (-3x + x2)) = 16 + -1(2x2)
Combine like terms: 3x + -3x = 0
(-9 + 0 + x2) = 16 + -1(2x2)
(-9 + x2) = 16 + -1(2x2)
Remove parenthesis around (2x2)
-9 + x2 = 16 + -1 * 2x2
Multiply -1 * 2
-9 + x2 = 16 + -2x2
Solving
-9 + x2 = 16 + -2x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x2' to each side of the equation.
-9 + x2 + 2x2 = 16 + -2x2 + 2x2
Combine like terms: x2 + 2x2 = 3x2
-9 + 3x2 = 16 + -2x2 + 2x2
Combine like terms: -2x2 + 2x2 = 0
-9 + 3x2 = 16 + 0
-9 + 3x2 = 16
Add '9' to each side of the equation.
-9 + 9 + 3x2 = 16 + 9
Combine like terms: -9 + 9 = 0
0 + 3x2 = 16 + 9
3x2 = 16 + 9
Combine like terms: 16 + 9 = 25
3x2 = 25
Divide each side by '3'.
x2 = 8.333333333
Simplifying
x2 = 8.333333333
Take the square root of each side:
x = {-2.886751346, 2.886751346}
