Given x-3 = √ 3, find the value of algebraic formula (x + 1) &# - 4 (x + 1) + 4

Given x-3 = √ 3, find the value of algebraic formula (x + 1) &# - 4 (x + 1) + 4

From x-3 = √ 3, if x = 3 + √ 3, then x + 1 = 4 + √ 3
(x+1)²-4(x+1)+4
=[(x+1)-2]²
=(2+√3)²
=7+4√3

If the square root of x > 3 is known, then the square root of | 3 - x | =?

If we know the square root of X ＞ 3,
Then the square root of | 3 - x | = the square root of x-3

Using computer to calculate the key sequence of root three minus root two is urgent!

3, root, minus, 2, root, equals

When using the calculator to calculate the formula - 3 + 1-7 + 2 + 4, what is the key sequence?

(-) 3 + 1 - 7 + 2 + 4 =
Note that (-) is a key that can be found on the calculator. Pressing 0-3 is also OK. The standard is that I should also pay attention to the equal sign
