Question

Bantuuu dong buat besok 7-10

Answer 1

7. 6x^ + 15 x - 14x -35 = 6x^ +x -35
8. 3p - 5 -4p^ +16p - 16 = 19p -4p^ -21
9. a + 1 + 2(a-2)/6a = 3a -3/6a
10. 4ab^ + 1/7 . 35 ac/12ab= 1b + 1/1 x 5 ac/3= 5 a^bc +1/3
Maaf kalo jawabannya salah

Answer 2

7. (3x-7)(2x+5) = 6x²+15x-14x-35
= 6x²+x-35
8. 3p-5-(2p-4)² = 3p-5-(4p²-16p+16)
= 3p-5-4p²+16p-16
= -4p²+19p-21
9. a+1 + a-2  = a+1 + 2(a-2)
    6a      3a            6a
= a+1+2a-4   = 3a-3  =  3(a-1)   = a-1
       6a              6a         6a          2a
10. 4ab²+1 x 35ac   =  5ab²+ac
          7       12ab         3ab
= 5a(b²+c)   = 5b²+c 
     3ab            3b
