The second power of (- 4x-3y) is equal to?

The second power of (- 4x-3y) is equal to?

16x^2+9y^2+12xy

The square of X - 4x + 4 is less than or equal to 0

X²-4x+4≤0
(x-2)²≤0
For any real number x, there are (X-2) &# 178; ≥ 0
So only X-2 = 0 holds
The solution is x = 2

A student is solving the equation 2x-1
A student solves the equation 2x-1 of 3. When the denominator is removed, THE-1 on the right side of the equation is not multiplied by 3, so the solution is x = 2. Try to find the value of a and find the correct solution

(2X-1)/3-4/3=-1 a=4/3
