There is no operator given an in such cases it is often taken to be multiplication eg ab = a*b Thus 2*(-4)*(3) = -24
To solve (184 + 243 + 808) - (109 + 72 + 84) evaluate the parentheses first: (184 + 243 + 808) - (109 + 72 + 84) = 1235 - 265 = 970
(2x-3)(2x+3) can be multiplied out using the FOIL method, which stands for: First Outer Inner Last This method only works for the multiplication of two binomials, so don't rely exclusively upon it....
(x+8)(x-1)=0x+8=0x=-8x-1=0x=1Therefore, the zeroes are -8 and 1.
-5 + (-2)? Negatives can be added, so it would be -7.
