Question

Ada yg tau gk? gw gk ngerti pls respon ya

Answer 1

2) (6a + 1) - (a - 3) = 5a + 4

3) (2t - 5)² = 4t² - 20t + 25

4) (3m + 2)(m - 5) = 3m² - 13m - 10

Answer 2

1.) 2k^2 - 5k+ k^2 + 3 +7k = 3k^2 + 2k + 3 (D)
2.) (sorry, no. 2 gw lupa caranya)
3.) (2t-5)^2 = 2t^2-20t+25 (D)
4.) (3m+2) (m-5)= 3m^2-15m+2m-10
                       = 3m^2-13m-10 (C)
