Study Notes
Area Calculation for a Chain of Boutiques
- Area expression: (12 + 7x + x^2) square meters
- Length: (x + 4)
- Given (x = 4)
- Required to compute dimensions without evaluating the area expression
Factoring Trinomials Exercise
- Factor the following trinomials:
- (x^2 + 5x + 4)
- (x^2 - 9x + 20)
- (x^2 - 3x - 28)
- (2x^2 + 16x + 14)
- (10x^2 - 13x - 3)
Finding Values for Factoring
- Determine values of (k) that allow factoring of:
- (x^2 + kx + 36)
- (x^2 + kx + 45)
- (x^2 - kx - 30)
Dimensions for Smartphone Area
- Area formula: (2x^2 + 9x + 10)
- Length: (2x + 5)
- Given (x = 5)
- Dimensions required without evaluating the area expression
Common Errors in Factoring
- Examine mistakes in the following:
- (x^2 + 16 \neq (x + 4)(x + 4))
- (1.6x^2 - 9 \neq (0.4x - 3)(0.4x + 3))
- (3x^2 - 27) can be factored but noted as prime
GCF and Monomials
