When multiplying two numbers together when negatives are involved, first multiply them together normally. In this case, 2x3=6
The next step is to find out if it's +6 or -6. You need to luck at the question again:
If we multiplied two positives, the answer is positive. If we multiplied two negatives, the answer is positive. Otherwise, the answer is negative.
In the question, we multiplied a positive by a negative, so the result will be negative. The answer, therefore, is -6
-2x+3+1=-7 -2x=-11 x=11/2
2x + 5 = -3 2x = -8 x = -8/2 x = -4
negative 15
(2x - i)(2x + i)where i is the square root of negative 1.x = 0.5i, -0.5i
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
-2x+3+1=-7 -2x=-11 x=11/2
2x + 5 = -3 2x = -8 x = -8/2 x = -4
Let square = [x] -4+3*(-2)*[-4]+[3x-2x]=-4-6-2+[x]=-12+[x]The answer is negative 12 plus squared x.
-x + 3x = 2x
2x+3 = -11 2x = -11-3 2x = -14 x = -7
negative 15
(2x - i)(2x + i)where i is the square root of negative 1.x = 0.5i, -0.5i
x= Negative 4
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
negative 15 plus positive three = negative twelve -15 + +3 = -12
negative one and a half
negative three
