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
x=-1 ^ how do you know?
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
plus or minus. You see it often with square roots. The square root of 9 is plus or minus 3.
2bc + 8b - 3c - 12 is an expression, not an equation or inequality. It cannot, therefore have "an answer".
2 minus 2/5 plus 1/2 minus 4 = -1.9
6xsquared minus 26x minus 5 over 3xsquared minus 15x
It is an equation and the value of n is 9
Without an equality sign and not knowing the plus or minus value of 5y it is not an equation.
The plus-minus sign (Â±) can be used to imply plus or minus within a sum. For example, one equation reads:-b Â± 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.
Overland - Plus or Minus 10 miles; Plus or minus 5 minutes Oversea - Plus or Minus 20 miles; Plus or minus 5 minutes
15x minus 8=minus 180 3x+8=24
Depends what type of equation you want. My favourite is the quadratic equation. (-B plus or minus the square root of B - 4AC) Divided by 2A
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus
A plus + a plus is a plus.
[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.
Yes that is correct
Yes: the equation is tautological!
