*Some Important Formulas are as follows:*

## Basic Algebra Formulas

### Square Formulas

- (a + b)
^{2 }= a^{2 }+ b^{2 }+ 2ab - (a − b)
^{2 }= a^{2 }+ b^{2 }− 2ab - a
^{2 }− b^{2 }= (a − b) (a + b) - (x + a) (x + b) = x
^{2 }+ (a + b) x + ab - (a + b + c)
^{2 }= a^{2 }+ b^{2 }+ c^{2 }+ 2ab + 2bc + 2ca - (a + (−b) + (−c))
^{2 }= a^{2 }+ (−b)^{2 }+ (−c)^{2 }+ 2a (−b) + 2 (−b) (−c) + 2a (−c) - (a – b – c)
^{2 }= a^{2 }+ b^{2 }+ c^{2 }− 2ab + 2bc − 2ca

### Cube Formulas

- (a + b)
^{3 }= a^{3 }+ b^{3 }+ 3ab(a + b) - (a − b)
^{3 }= a^{3 }– b^{3 }– 3ab(a – b) - a
^{3 }− b^{3 }= (a − b) (a^{2 }+ b^{2 }+ ab) - a
^{3 }+ b^{3 }= (a + b) (a^{2 }+ b^{2 }− ab) - (a + b + c)
^{3 }= a^{3 }+ b^{3 }+ c^{3 }+ 3(a + b)(b + c)(c + a) - a
^{3 }+ b^{3 }+ c^{3 }− 3abc = (a + b + c) (a^{2 }+ b^{2 }+ c^{2 }− ab − bc − ac) - If (a + b + c) = 0, a
^{3 }+ b^{3 }+ c^{3 }= 3abc

### Special Case Formulas

a ^{n }− b ^{n }= (a − b) (a ^{n−1 }+ a ^{n−2 }b ^{1 } + a ^{n−3 }b ^{2 }+ …. + a ^{1 }b ^{n−2 }+ b ^{n−1 })

- √a = a
^{1/2} - ∛a = a
^{1/3} ^{n }√a = a^{1/n}- a
^{p. }a^{q }= a^{p + q} - a
^{p }/ a^{q }= a^{p – q} - a
^{p. }b^{p }= (ab)^{p} - (a
^{p })^{q. }= a^{pq} - a
^{0 }^{. }= 1 - a
^{–n. }= 1/a^{n}

**Quadratic Formula: **The roots of a quadratic equation ax^{2} + bx + c = 0 are given by x = [-b ± √(b^{2} – 4ac)]/2a.
