The solution
You have entered
[src]
2 a + 10*a + 25 + (a + 5)*(5 - a) = 0
$$\left(5 - a\right) \left(a + 5\right) + \left(\left(a^{2} + 10 a\right) + 25\right) = 0$$
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without a)
from left part to right part, we given:
$$10 a = -50$$
Divide both parts of the equation by 10
We get the answer: a = -5
a^2+10*a+25+(a+5)*(5-a) = 0
Expand expressions:
a^2 + 10*a + 25 + 25 - a^2 = 0
Reducing, you get:
50 + 10*a = 0
Move free summands (without a)
from left part to right part, we given:
$$10 a = -50$$
Divide both parts of the equation by 10
a = -50 / (10)
We get the answer: a = -5
