∙ 14y ago√(x-3) = x-5
x-3 = (x-5)2
x-3 = x2 -10x+25
0=x2-11x+28
0=(x-7)(x-4)
x-7=0, x-4=0
x=7, x=4
Check:
√(7-3) = 7-5
√4 = 2
2=2
yes
√(4-3) = 4-5
√1 = -1
no

Which is the best way to solve the equation x2 equals n?
Take the square root of both sides of the equation
What square root property is essential to solve any radical equation involvine a square root?
What square root property is essential to solve any radical equation involving square root?
What is the square root of 2x plus 1 equals 3?
The answer will depend on how far the square root sign goes.If you want to solve for "x", I suggest you isolate the square root on the left (if it only covers the "2x" part, move the "1" to the other side of the equation). Then, if you square both sides of the equation, you get a formula which you can easily convert to a form which can be solved with the quadratic equation.

What is the answer to 4 square root 25 x square root 120?
To solve this problem, you must first solve the smaller problems. The square root of 25 is 5, and the square root of 120 is 10.95. First solve the equation on the left side of the multiplication sign, which is 4 x 5. Now, multiple the answer of 20 by 10.95, which is 219.
Which is the best way to solve the equation the square root of x equals m?
It depends on which variable you wish to solve for.
Which is the best way to solve the equation x2 equals n?
Take the square root of both sides of the equation

What square root property is essential to solve any radical equation involving square root?
If you take an equation such as Ax2+ Bx+c=0, you can complete the square and then use the square root property to solve it. That is how we derive the quadratic equation. For example, x2+2x-9=0 We write this as (x+1)2=10 bu completing the square then the square root property tell us that x+1 is PLUS OR MINUS Square root of 10
Which of the following are techniques you have learned so far to solve a quadratic equation?
Solve by factoring. Solve by taking the square root of both sides.
