Answer 1

A. x^2 - 5x + 5x - 25 >> x^2 -25
b. x^2 + 7x - 7x - 49 >> x^2 - 49
c. 2ab - 6a + 6b - 18
d. 3x^2 + 9x - 33x - 99 >> 3x^2 - 24x - 99
e. 35ab - 35a + 35b - 35
f. x^2 + 4x + 9x + 36 >> x^2 + 13x + 36

^ = pangkat

Answer 2

A. (x+5) (x-5) = x²-5x+5x-25
= x²+25
b. (x-7) (x+7) = x²+ 7x-7x-49
= x²-49
c. (2a+6) (b-3) = 2ab -6a+6b-18
d. (x-11) (3x+9) = 3x²+9x-33x-99
= 3x²-24x-99
e. (5a+5)( 7b-7) = 35ab-35a+35b-35
f.(x+9) (x+4) = x²+4x +9x+36
x²+13x+36
