Question

1.Jabarkan dan sederhanakanlah!
a. (a + 3)(2a² - a - 3)
b. (2a - )²
c.(3p - 3)² - 2(2p - 1)²

Maaf yahh.. Saya Butuh Bangett,,

Answer 1

1. (a + 3) (2a²-a-3)
  = (2a³-a²-3a) + (6a²-3a-9)
  = 2a³ - a² + 6a² - 3a -3a- 9
  = 2a³ + 5a² - 6a - 9

3. (3p - 3)² - 2(2p-1)²
   = (3p-3) (3p-3) -2 (2p-1) (2p-1)
   = (9p² - 9p -9p + 9) - 2( 4p²-2p-2p+1)
   = 9p² - 8p² - 18p + 8p + 9 - 2
  = p²- 10p + 7

2. (2a - ²
  = ²
  = ×
  =
  =

btw, cmiiw .
Hope this help.
