Quadratic Equation
स्टोरीबोर्ड पाठ
- x2 + 9x + 20
- Now that we have an equation, we will able to perform a math magic. It figures out what two numbers are factors of the top number that add to equal the bottom number.
- 5
- 20
- 9
- 4
- x2 + 9x + 20
- It then creates a new factorable equation by turning the middle term into two separate terms.
- 5
- 20
- 9
- 4
- x2 + 5x + 4x + 20
- x2 + 9x + 20
- What do we do with the new equation?
- 5
- 20
- 9
- 4
- x2 + 5x + 4x + 20
- x2 + 5x + 4x + 20
- (x + 4)(x + 5)
- x(x + 5) + 4(x + 5)
- We split it into two groups and from there we can pull out what is in common with the terms in each.
- (x2 + 5x) + (4x + 20)
- Show me!
- Wow!! That was super easy! Thanks-a-lot!
