Question

simplify (3x-y+2z)²-(3x-y-2z)²​

Answer 1

Answer:

)^2=(3x+2y)^2

(2x+3y) = (3x+2y); (2x+3y) = -1(3x + 2y) (Take the square root of both sides)

(2x+3y) = (3x+2y); (2x+3y) = (-3x-2y) (Distribute out the -1)

(2x+3y-2x) = (3x+2y-2x); (2x+3y-2x) = (-3x-2y-2x) (Subtract 2x from everything)

3y = x+2y; 3y = -5x-2y (Simplify)

3y-y = x+2y-y; 3y = -5x-2y (Subtract y from both sides on the left equation)

2y = x+y; 3y = -5x-2y (Simplify the left equation)

2y = x+y; 3y+2y = -5x-2y+2y (Add 2y to both sides of the right equation)
