Find the solutions to the equation below.
Check all that apply.
x2 - 25 = 0
A. X= 3
B. x = -5
C. X = 1
D. X = -3
E. x = 5
I F. x = -1

x = -5, 5

Step-by-step explanation:

x^2 - 25 = 0

Add 25 to each side

x^2 -25+25 = 0+25

x^2 = 25

Take the square root on each side

sqrt(x^2) = ±sqrt(25)

x = ±5

x = + 5

Explanation: To solve the equation x² - 25 = 0, our first step is to get the x² term by itself by adding 25 to both sides of the equation.

On the left side of the equation, the -25 and +25 cancel out and we have x² and on the right side of the equation, 0 + 25 is 25.

So we have x² = 25².

Now to get x by itself, we take the square

root of both sides of the equation.

On the left, the square root of x² is x snd on the right, since 25is the perfect square 5 · 5, the square root of 25 is 5 and don't forget to use plus or minus when taking the square root of both sides of an equation.

So our answer is x = + 5.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
