"x" would equal 1 because 7/1 is 7 minus 2 equals 5 and 3/1 is 3 plus or + 2 is 5.
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
16
2bc + 8b - 3c - 12 is an expression, not an equation or inequality. It cannot, therefore have "an answer".
15x minus 8=minus 180 3x+8=24
2 minus 2/5 plus 1/2 minus 4 = -1.9
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
negative b plus or minus the square root of b minus 4 times ac all over 2 a
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
x=-1 ^ how do you know?

The plus-minus sign (±) can be used to imply plus or minus within a sum. For example, one equation reads:-b ± sqrt (b2 - 4ac)This refers to an equation with two possible solutions - that from which you use the plus sign, and that from which you use the minus sign.
plus or minus. You see it often with square roots. The square root of 9 is plus or minus 3.
2 minus 2/5 plus 1/2 minus 4 = -1.9
15x minus 8=minus 180 3x+8=24
It is an equation and the value of n is 9
