X2 + 10X - 13 = 17 add 13 to each side X2 + 10X = 30 halve the linear coefficient ( 10 ), square it and add it to both sides X2 + 10X + 25 = 30 + 25 factor on the left and gather terms on the right (X + 5)2 = 55 (X + 5)2 - 55 = 0 ---------------------------vertex form, (- 5, - 55 ), is the vertex -------------------------------------------[-------------------------------]
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
No, it becomes a plus, since minus x minus = plus
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
3x squared minus 25x minus 28
2013 minus 1958 = 55
(-45) - (-55) *Minus plus is equals to minus.( -,+ = - ) minus minus is equal to plus (-,- = + ) and plus plus is equal to plus (+,+ = +) so the ans is that, (-45) +55 -45 + 55 (+10)ans Greater value sign has been used, which is 55 so the ans is +10.
55 - 1.5 = 53.5
It is: 55 -28 = 27
55 - 12= 43
90 - 55 = 35
56 - 55 = 1
18.
45 - 100 = -55
136 minus 81 is 55.
