Simplify: Distribute
1) 3(x + 2)
2) -4(x + 5)
3) – (x – 7)
4) 5(4x – 13)
5) 8(-2x + 5)
6) 4(-3x – 1)
Simplify : Distribute
1) 3(x + 2) = 3x + 6
2) -4(x + 5) = -4x – 20
3) – (x – 7) = -x + 7
4) 5(4x – 13) = 20x – 65
5) 8(-2x + 5) = -16x + 40
6) 4(-3x – 1) = -12x – 4
Simplify: Combine like terms
1) 5x + 7 + 3x – 4
2) 2x 2 + 9x + 4 + 6x 2 - 2x +17
3) 3x 3 - 5x 2 - x + 4 + x3 + 2x 2 + x - 2
4) -x – 6 – 3x – 1
Simplify: Combine like terms
1) 5x + 7 + 3x – 4 = 8x + 3
2) 2x 2 + 9x + 4 + 6x 2 - 2x +17 = 8x 2 + 7x + 21
3) 3x 3 - 5x 2 - x + 4 + x3 + 2x 2 + x - 2 = 4x3 - 3x 2 + 2
4) -x – 6 – 3x – 1 = -4x – 7
Simplify: Distribute and Combine Like
Terms
1) 4 – 5(2x + 7)
2) -7(4 – x) + 9x
3) -6x + 8(-3 + 4x)
4) 2(x – 4) + 3(x + 5)
5) 9(4 – 7x) – 3(2 + 5x)
6) -5(2x – 3) + 7(x – 1)
Simplify: Distribute and Combine Like
Terms
1) 4 – 5(2x + 7) = 4 – 10x – 35  -10x – 31
2) -7(4 – x) + 9x = -28 +7x + 9x 16x – 28
3) -6x + 8(-3 + 4x) = -6x – 24 + 32x  26x – 24
4) 2(x – 4) + 3(x + 5) = 2x – 8 + 3x + 15  5x + 7
5) 9(4 – 7x) – 3(2 + 5x) = 36 – 63x – 6 – 15x 
-78x + 30
6) -5(2x – 3) + 7(x – 1) = -10x + 15 +7x – 7 
-3x + 8
