X^2 - 25 = 0
Add both sides by 25
x^2 = 25
Take the positive and negative square root.

x = 5
OR
x = -5

Answer:

there are two solutions are x = (+5) and x = (-5)

Step-by-step explanation:

The given quadratic equation is x² - 25 = 0

Now we can get the solutions of this equation by zero factors.

[ since (a² - b²) = ( a-b ) ( a+b ) ]

so x² - 25 = (x-5) (x+5)

( x-5 ) = 0 ⇒ x = 5

or x + 5 = 0 ⇒ x = -5

Therefore, there are two solutions are x = (+5) and x = (-5)

Answer: x=6, y=20

Step-by-step explanation:

Since ΔBCD and ΔTUS are congruent triangles, we can set the sides equal to each other.

y=2y-20                           [subtract both sides by 2y]

-y=-20                              [divide both sides by -1]

y=20

--------------------------------------------------------------------------------------

3x+32=9x-4                    [add both sides by 4, and subtract both sides by 3x]

36=6x                              [divide both sides by 6]

x=6
