To find the inverse you switch the x and the y and then solve for y. x=2 radical( y + 3) radical(y + 3) = x/2 y+3= (x/2)² y = (x/2)² -3 So the answer is y = (x/2)² -3
√3 x √21 = √3 x √(3 x 7) = (√3 x √3) x √7) = 3√7
A radical is considered to be in simplest terms when:There is no fraction under the radical sign. For example, root(2/3) should be converted to root(2) / root(3) - and then, the other rules should be applied. There is no radical in a denominator. In the above example, you continue multiplying numerator and denominator by root(3), so you obtain root(6) / 3.No perfect square appears as a factor under a radical sign. For example, root(12) should be changed to root(4 x 3) = root(4) x root(3) = 2 root(3).A radical is considered to be in simplest terms when:There is no fraction under the radical sign.

Equations will have an equals sign. Such as: x + 3 = 2 Polynomials will not. Such as: 2x + 3
4 x2
Radical (3x) = radical(x) * radical(3).
"Radical x times radical x" could be interpreted as the square root of x times the square root of x - in which case the product would be x (the number under the radical sign)
To find the inverse you switch the x and the y and then solve for y. x=2 radical( y + 3) radical(y + 3) = x/2 y+3= (x/2)² y = (x/2)² -3 So the answer is y = (x/2)² -3
30 degrees explanation 2Cosx-radical 3=0 Then 2cosx=radical 3 and cos x=(radical 3)/2 Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle. So the answer is 30 degrees.

It is a quadratic equation and can be rearranged in the form of:- x2-x-6 = 0 (x+2)(x-3) = 0 Solutions: x = -2 and x = 3
X + 4 = 7The answer is 3. To find the answer, take 4 away from both sides of the equals sign. You are left with x on the left and 3 on the right, so x = 3.
You can move it up or down by adding a constant, call it c. Let c>0 Y=radical(x)+c move it up c and y= radical(x)-c moves it down c. You can move it to the right by subtracting c inside the radical sign. Let c>0 y=radical (x-c) moves it to the right c units. y=radical (x+c) moves it to the left c units.
The square root of 60 is the square root of 2 x 2 x 3 x 5. When that is simplified, a 2 comes out from under the radical sign, resulting in a final answer of 2 radical 15.
x = 2 is an algebraic equality (Because there is an 'equals'(=) sign) x - 2 is an algebraic expression ( Because there is NO equals sign).
Equations will have an equals sign. Such as: x + 3 = 2 Polynomials will not. Such as: 2x + 3
