Jika p = √ a² + 10ab + 25b² dan q = 2a + b hasil p+q =

p = √(a²+10ab + 25b²)
p= √(a+5b)²
maka p= a+5b
di tanya p+q
maka
p + q
a + 5b + 2a + b
= 3a + 6b
done

[tex]p = \sqrt{ {a}^{2} + 10ab + 25 {b}^{2} } \\ = \sqrt{(a + 5b)^{2} } \\ = a + 5b \\ \\ q = 2a + b \\ \\ p + q = 3a + 6b = 3(a + 2b)[/tex]
