Algebra 1 Chapter 7 Factoring

18) Find the dimensions of the polygon with the given area: Area = 55 ft^2 Length = (x - 10) ft Width = (x - 4) ft

L = 11 W = 5

Factor: 9x^2 - 48x + 64

(3x - 8)(3x - 8)

Factor: 16x^2 - 25

(4x + 5)(4x - 5)

Put into standard form: 5x - 4x^5 + 3x^2 - 7

-4x^5 + 3x^2 + 5x - 7

Divide: 9x^2 + 3x −42 and 3x - 6

3x + 7

Factor: 81x^2 − 169y^2

(9x - 13y)(9x + 13y)

Factor: xy + 2y + 3x + 6

(x + 2)(y + 3)

Find the GCF: 36a5 + 24a3 - 12a

12a

Factor: 10x^2 + 24x + 8

2(x + 2)(5x + 2)

Simplify: (5x + 6)^2

25x^2 + 60x + 36

Simplify: (4x^2 + 6x − 4) − (2x^2 − 15x − 7)

2x^2 + 21x + 3

Simplify: (3x + 13)(2x − 2) − (2x − 5)(x − 2)

4x^2 + 29x - 36

Multiply: (x − 4)(4x + 7)

4x^2 - 9x - 28

Simplify: 7y^2 + 3y + 6 − 2(y^2 − 7y − 8)

5y^2 + 17y + 22

Divide: 9x^2 - 4x + 25 by x + 4

9x - 40 + 185/(x + 4)

Solve: 2x^2 - 5x - 3 = 0

x = 3, x = -1/2
