Exponent laws – These laws help us to solve terms which have exponent or powers.
1. (x m)(y n) = ym + n
2. (xy) m = x m y m,
3. (x m) n = x mn,
4. x0 = 1,
5. (x m)/(y n) = x m – n,
6. x -m = 1 / (x m).
1. (x + y)1 = x + y,
2. (x + y)2 = x2 + 2xy + y2
3. (x + y)3 = x3 + 3x2y + 3xy2 + y3
4. (x + y)4 = x4 + 4x3y + 6x2y2 + 4xy3 + y4
5. (x - y)2 = x2 - 2xy + y2
6. (x - y)3 = x3 – 3 x2 y + 3xy2 - y3
7. (x – y) 4 = x4 - 4x3y + 6x2b2 - 4xy3 + y4
8. (x2 – y2) = (x + y) (x – y).
Now we will discuss some basic Math formulas which can be used to solve quadratic equations:
Quadratic equation are of form ax2 + bx + c = 0. Formula to solve these types of equations is called as quadratic equations.
x = -b $\pm$ √(b2 – 4ac) / 2a.
This formula finds value of 'x' in given Quadratic Equation.
Now we will see some important rules involving zero.
0 / x = 0,
x0 = 1,
0x = 0,
x * 0 = 0,
x / 0 = Not defined.
Above algebraic formulas list can be used to solve basic algebraic problems which can range from very simple to very complex problems.
