Only one. 2x - 12x = 220 -10x = 220 x= 220/-10 x = -22
Just one.
Since that isn't an equation, there is really nothing to solve.
Just the one because if: 12x+6 = 5x then x = -6/7
2y-12x=-6 is the equation of a line. It has infinite number of solutions which are all the points one the line. We can rewrite the equation as 2y=12x-6 and then divide both sides by 2.This gives us y=6x-3. From this we know the equation describes a line with y intercept -2 and slope 6.
If you mean: 3x^2+12x+12 = 0 then it has two equal solutions of -2
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
x2 - 12x + 35
Only one. 2x - 12x = 220 -10x = 220 x= 220/-10 x = -22
Just one.
Since that isn't an equation, there is really nothing to solve.
Just the one because if: 12x+6 = 5x then x = -6/7
None because without an equality sign the given expression is not an equation.
b
12x-8y
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0 → x = (-(-3) ±√((-3)² - 4×1×1))/(2×1) → x = (3 ±√5)/2 → x = (3 + √5)/2 or x = (3 - √5)/2
