Question

A.(4x-3y)×(x+2)
b.(2x-3)(x2-2x+3)
c.(10b7:5b5):2b2
d.(4y5×x4y4):8y5

Answer 1

A.  (4x - 3y) (x +2)
  = 4x² + 8x - 3xy - 6y

b.  (2x - 3) (x² - 2x + 3)
  = 2x³ - 4x² + 6x - 3x² + 6x - 9
  = 2x³ - 7x² + 12x - 9

c. (10b7 : 5b5) : 2b2
  = 2b² : 2b²
  = 1

d. (4y5 x 4v4 ) : 8y5
  = 16y9 : 8y5
  = 2y4

semoga benar dan bisa membantu :)
