## Algebra 1 Formulas

Algebra basics formula helps in speeding up the calculation part. Some of the algebra formula include:

(a+b)= a+ b2 + 2ab

(a-b)= a+ b- 2ab

(a+b)3 = a3 +b+ 3ab (a+b)

(a-b)= a- b- 3ab (a-b)

## Algebra 1 Problems

Below you could see examples

### Solved Examples

Question 1: solve for x,

x - $\frac{1}{2}$ = 2
Solution:
Given: x - $\frac{1}{2}$ = 2

Take $\frac{1}{2}$ on both sides

x = 2 + $\frac{1}{2}$

x = $\frac{5}{2}$

Question 2: Factorize, x2 + 5x + 6 = 0
Solution:
Given: x2 + 5x + 6 = 0

x2 + 3x + 2x +6 = 0

x(x + 3) + 2( x + 3) = 0

(x + 3) (x + 2) = 0

x = -3

x = -2
