Hello, so here we have the quantity, t minus 1 1ā2 squared is equal to a negative 17 force.
00:07
So to solve this, well, we want to take the square root of both sides, which is just going to give us t minus 1 half, is then going to be equal to positive or negative the square root of negative 17 force.
00:22
Okay, well, we can see that this is not going to have any solutions in the real numbers because the square root of negative 17 force.
00:28
Right, this is not a real number.
00:29
Can't think the square root of a negative.
00:32
But what we keep going to solve this, so we have t minus one half.
00:38
It should be one half here, right? okay, so we just add one half to both sides, and what do we have? we have that t is going to be equal to one half, and then plus or minus the square root of negative 174s, which is going to be equal to one half, and then we get a plus or minus, the square root of negative 17 .4 is going to be, well, it's going to be the square root of 174's i, which the square root of 17 over square root of four...
