x2 + 6x + 9 = 81 x2 + 6x = 72 x2 + 6x - 72 = 0 (x+12)(x-6) = 0 x= -12, 6 (two solutions)
12 + 12 + 12 + 191 = 227
-27
Plus 12 plus -13 plus plus 1 can be rewritten in mathematical terms as: 12+(-13)+1 or 12-13+1 12-13+1 =-1+1 =0
(x4 + y4)/(x + y) = Quotient = x3 - x2y + xy2 - y3 Remainder = - 2y4/(x+y) So, x3 - x2y + xy2 - y3 - 2y4/(x+y)
If you mean: 4x -3y = 1 and x -2y = 4 then the solutions are x = -2 and y = -3
Set it equal to 0 and subtract x and solve for y
2y4(16 - x4) = 2y4 (4 + x2)(4 - x2) = 2y4(4 + x2)(2 + x)(2 - x)

None because without an equal it is not an equation. But if it was in the form of x2+7x+12 = 0 then it would have 2 solutions which are x = -3 and x = -4
zero solutions. If you plot these two lines, you will see that they are parallel and do not intersect.
An expression cannot be solved: only an equation or inequality has solutions.
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
There are infinite solutions, since you have 2 unknowns and 1 equation. x+4y=12 4y=12-x y=3-0.25x or x=12-4y If you choose an y or an x, the other is defined.
There are 120 solutions.
