Solve: Vx+1= Vx+6 -1
Squaring both sides of the equation results in
which of the following?
x+1= x + 6-1
x+1= x + 6 +1
x+1= x+7+2VX-6
x+1= x+7-2Vx+6

Step-by-step explanation:

Squaring both sides of the equation would give which then simplifies to

We can then subtract 7 from both sides to get

Then we can subtract x from both sides, which cancel out and we get

Then we need to divide both sides by -2 to get

Then we need to square both sides to get rid of the square root to get 9 = x + 6

Then finally subtracting 6 from both sides we get 3 = x

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
