7 plus 2 is 9. 9 plus 8 is 17. 17 plus 3 is 20.
-7 + 6 x 17 -7 + 102 = 95
A quadratic equation. If you wish to solve for x, you can do so as follows: -x2 + 6x + 7 = 0 x2 - 6x - 7 = 0 (x - 7)(x + 1) = 0 x ∈ {-1, 7}
x2 + 7x = 0 => x*(x + 7) = 0 => x = 0 or x + 7 = 0 so that x = 0 or x = -7
c= -2 2/7 OR -2.285714
p is obviously zero because any number x plus 0 equals itself.

If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
To solve the equation (X^2 + 14X + 49 = 0), you can factor it as ((X + 7)^2 = 0). Setting this equal to zero gives (X + 7 = 0), leading to the solution (X = -7). Alternatively, you could use the quadratic formula, but in this case, factoring is simpler.
To solve the equation (5x - 17 - x + 7 = 0), first combine like terms. This simplifies to (4x - 10 = 0). Next, add 10 to both sides to get (4x = 10), and then divide by 4. Thus, (x = \frac{10}{4} = 2.5).

12x + 17 = 7 Subtract 17 from both sides: 12x = -10 Divide both sides by 12: x = -10/12 = -5/6
