1 ) John and Sarah happen to be simplifying this kind of expression.

3a + 8b + 7a – 6b

John says the answer is definitely 2a + 2b and Sarah according to the answer is 10a & 14b. What is the correct response?

Sarah

2 . Simplify these types of expressions.

a) 4d + 6e – 2d – 3e sama dengan 2d-3e

b) 12g – 3h – 8g & h = 4g-4h

c) k + 2k & 3k – m – 2m – 3m = 6k-3m

d) 7c + 4d – 10c + 5d sama dengan -3c+9d

several. Multiply out these conference.

a) 3(2a + 7) = 6a+21 b) 5(3x – 2y) = 15x-10c) 2(4g2 – 3g) = 8g2-6

four. Expand the brackets and then simplify the expression.

a) 2(x + 8) + 3(x + 1) = 2x+16+3x+3 = 5x+19

b) 3(2x + 3) + 2(2x – 3) = 6x+9+4x-6 = 10x+15

c) 4(2a – 5) + 3(a – 1) = 8a-20+3a-3 = 11a-23

d) 2(4a + 1) – 2(a – 1)= 8a+2-2a-2 sama dengan 6a

five. Factorise these types of expressions simply by removing one common factor.

a) 4a & 6 sama dengan 2(2a+3)b) 9x – 6 = 3(3x-2)c) 7g2 – 2g sama dengan g(7g-2) d) 4b2 & 6b sama dengan b (4b+6)e) 12x2 + 3x sama dengan 6x(2x f) 6ab – 9a = 3a(2b-3)

6. The formula pertaining to working out the perimeter of the rectangle is P sama dengan 2(b + h) wherever b is a base length and they would is the elevation. The solution for the perimeter of any square is usually P = 4s where s is definitely the length of each side of the sq.

h

h

b
