Answer:
0
Step-by-step explanation:
Make and equation and solve for x.
(2x+10)^2 = 4(x-5)^2 Now the easiest thing to do is use the formula for squared binomial, (a+b)^2 = a^2 + 2ab + b^2.
4x^2 + 40x + 100 = 4(x^2 - 10x + 25)
4x^2 + 40x + 100 = 4x^2 - 40x + 100
From hear you can cancel out similar terms
40x + 100 = - 40x + 100
40x = -40x
add 40x to both sides
80x = 0
x = 0
The only solution to this is 0.
