A halogenoalkane is a saturated hydrocarbon chain with a halogen atom (F, Cl, Br or I) attached to a carbon instead of a hydrogen. Halogens have a greater electronegativity than carbon. This means they dr...
We need to get the quadratic expression into the form (x + a)(x + b). If we expand this expression using FOIL, we see that the resulting expression is x2 + (a+b)x + ab. We can now find a and b ...
Increase the powers of all variables by one and then divide them by this number. For example, given 3x^3 + 5x^-0.5 - 8 , this would give 3/4x^4 + 10x^0.5 - 8x
The power of a number indicates how many times that number must be multiplied by itself. If the power is a negative, this means that the number (or the base) is a fraction, with the base as a denominator....
