Question

Please pake caranya yaa...

Answer 1

3. a. (x+1) (x+2) = x² +2x+x+2 = x²+3x+2
     b. (x+a) (x+b) = x² +bx+ax+ab = x²+x(a+b)+ab
     c. (x-1) (x-2) = x² -2x-x+2 = x²-3x+2
   d.(x-a) (x-b) = x² -bx-ax+ab = x²-x(b+a)+ab
6. a. (3x+2y)(x-y+2) = 3x² - 3yx +6x+2yx-2y²+4y
     =3x²-2y²-yx+6x+4y
