I'm pretty sure you're looking for the coordinates of the equation, not the "answer". Since it's already in Standard Form (x2 - 10x + 9 = 0) all you have to do is factor it. Basically it'd be (x - 10)(x + 9) = 0 Then use the zero property, which would turn BOTH answers to the equations 0. (x - 10) = 0 x= 10 (x + 9) = 0 x= -9 AND THERE YA GO! The solutions are 10 and -9, check them in the original equation!
-14
x = 7
it equals 2 i done it on my scientific calculator
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
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
It is: 2x2-7x+6 = (2x-3)(x-2) when factored
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
-7
I'm pretty sure it's x sqaured plus seven
3-(-9) Considering a negative plus a negative equals a positive your equation can be rewritten as 3+9 Which equals 12
Minus 8 plus 6 equals -2.
