Sederhanakanlah bentuk aljabar berikut ini!

Jawaban:

a. 6(3x+1)-x(3x+1) = 18x+6-x^2-x = -x^2+17x+6

b. x^2(x^2+2) – 2(x^2+2) = x^4+2x^2 – 2x^2 – 4 = x^4 – 4

c. (x^2 – 4)^2 = x^4 – 2.4.x^2 + 16 = x^4 – 8x^2 + 16

d. 5a(7b-7) + 5(7b-7) =35ab – 35a + 35b – 35

e. x(3x+9) – 11(3x+9) = 3x^2 + 9x – 33x – 99 = 3x^2 – 24x-99

f. x(x-y+3) – y(x-y+3) + 2(x-y+3) =x^2 – xy+3x -xy-y^2 – 3y + 2x-2y+6 = x^2+5x-y^2-5y+6
