The 'answer' is the number that 'x' must be in order to make the equation true.
(x + 3) (x + 3) = 36
Expand the left side:
x2 + 6x + 9 = 36
Subtract 36 from each side:
x2 + 6x - 27 = 0
Factor the left side:
(x + 9) (x - 3) = 0
This equation is true if either factor = 0:
x + 9 = 0 ===> x = -9
x - 3 = 0 ===> x = 3
Both values for 'x' are "answers" to the original equation.
A simple equation, true when w = -4
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
9 divided by 9 equals 1, and 3 times 12 equals 36. 1 plus 36 equals 37.
It is an equation with the plus or minus signs missing which makes it impossible to solve.
A circle centre (0, 0) and radius r has equation x² + y² = r² The circle x² + y² = 36 has: r² = 36 → radius = 6

sqrt 36 ie 6
36
this equation makes no sense, 6% of what?
9 divided by 9 equals 1, and 3 times 12 equals 36. 1 plus 36 equals 37.
52 times 36 equals 1,872, plus 17 equals 1,889.
It is the equation of a circle with radius of 6 and its center at the origin.
The domain and range are both [-6, +6].
It is an equation with the plus or minus signs missing which makes it impossible to solve.
