Solution for =(10x+25)(10x+25) equation:


Simplifying
0 = (10x + 25)(10x + 25)

Reorder the terms:
0 = (25 + 10x)(10x + 25)

Reorder the terms:
0 = (25 + 10x)(25 + 10x)

Multiply (25 + 10x) * (25 + 10x)
0 = (25(25 + 10x) + 10x * (25 + 10x))
0 = ((25 * 25 + 10x * 25) + 10x * (25 + 10x))
0 = ((625 + 250x) + 10x * (25 + 10x))
0 = (625 + 250x + (25 * 10x + 10x * 10x))
0 = (625 + 250x + (250x + 100x2))

Combine like terms: 250x + 250x = 500x
0 = (625 + 500x + 100x2)

Solving
0 = 625 + 500x + 100x2

Solving for variable 'x'.

Combine like terms: 0 + -625 = -625
-625 + -500x + -100x2 = 625 + 500x + 100x2 + -625 + -500x + -100x2

Reorder the terms:
-625 + -500x + -100x2 = 625 + -625 + 500x + -500x + 100x2 + -100x2

Combine like terms: 625 + -625 = 0
-625 + -500x + -100x2 = 0 + 500x + -500x + 100x2 + -100x2
-625 + -500x + -100x2 = 500x + -500x + 100x2 + -100x2

Combine like terms: 500x + -500x = 0
-625 + -500x + -100x2 = 0 + 100x2 + -100x2
-625 + -500x + -100x2 = 100x2 + -100x2

Combine like terms: 100x2 + -100x2 = 0
-625 + -500x + -100x2 = 0
