Algebra for Basic Skills

Simplify the following expression:
3 + 5x + 8 - 2x

• -3x² - 11
• 3x² + 11
• 11 - 3x
• 11 + 3x

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4
• 2a + 2b + 4
• 8ab
• 4ab + 4

5a + 2b - 7b + 4a

• 7b - 3a

• 9a - 5b

• 4ab

• 12a + 6b

2(3x+7) = x +10 +5x + 4

• 2
• -4
• no solution
• all real numbers

3(x + 3) + 2(4x - 4) = 12

• 4

• 3

• 2

• 1

Solve for x:
4 - 2(x - 3) = 24

• - 7
• 7
• 14
• - 14

Solve:  $4\left(2-x\right)-\left(x-8\right)=-4$ 

• No solution

• Infinite many solutions

•  $-\frac{4}{5}$  

•  $4$  

Simplify the following expression:  
(-x - 3)(x + 5)

• -x² + 2x - 15
• -x² - 8x - 15
• x² + 2x - 15
• -x² - 8x + 15

(x + 5)² 

Hint: try (x + 5)(x + 5)

• x² + 25
• x² + 10x + 25
• x² + 10 x + 10
• x² + 10

Find the product:
(3x + 2)(2x + 4)

• 6x² + 16x + 8
• 5x² +11x + 6
• 5x² + 16x + 6
• 6x² + 11x + 8
