Question

Tolong jawab ya soal MTK, please :')

Answer 1

1. -5(x+2) -2(3x^2) = -5x -10 -6x^2
2. -8x (2x+2y) = -16x^2 - 16y
3. (2a+6) (a-3) = 2a^2 - 18
4. (X+5) (x-5) = x^2 - 25
5. (3x+7) (2x-3) = 6x^2 +5x -21
6. 9x4y / x^2 = 36y/x
7. 54a^4 bc^8 / 13 b^2 = (54 a^4 c^8) /13

Answer 2

1.= -5(x+2) - 2(3x2)
=-5x-10-2(6)
=-5x-10-12
=-5x-22
2.= -8x(2x+2y)
= -16x-16xy
3.= (2a+6).(a-3)
=2a²-18
