= a²- ab + ab - b²
= a² - b²
2.a. (a+b)(a+b)
= a² + ab + ab +b²
= a² + 2ab + b²
b. (a-b)(a-b)
= a² - ab - ab + b²
= a² - 2ab + b²
c. (ax+b)(cx+d)
= acx² + bcx + adx + bd
4. memakai rumus : (a+b)² = a² + b² + 2ab
maka :
(6)² = a² + b² + 2(4)
36 = a² + b² + 8
a² + b² = 36 - 8
a² + b² = 28
jadi, jumlah kuadrat bilangan itu adalah 28
