Your question does not make sense. It would probably be interpreted as a + = ++a ---a
Solve using the quadratic formula
By including its plus or minus signs
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
15x minus 8=minus 180 3x+8=24
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
x = 25 / 3squared + 5
It is an equation with the plus or minus signs missing which makes it impossible to solve.
