So we have asked to solve 7 minus 7 x equals to 3x plus 2, multiplied by x x minus 1.
00:18
So we can just see on the right hand side here we have, we can multiply this to terms.
00:26
So we have 7 minus 7 x equals to 3x squared, negative 3x, 2x, 2, 2.
00:37
Negative 2.
00:38
We just have to simply multiply.
00:40
So we have 7 minus 7 x equals to 3x squared and then negative x then negative 2.
00:48
So you want to solve this equation.
00:51
Therefore we have to make the right -hand side of this equation to 0.
00:56
So what i'm talking about is we have to make this equation looks like this form a x squared plus v x was well let's say any number equals to 0.
01:08
So we can solve, we can find the value of x.
01:12
So we can just move all of this number to the left -hand side.
01:17
So we get zero on the right -hand side.
01:19
So we have 7 -7 -x, minus 3x squared plus x plus 2 equals to 0, right? looks like this form here.
01:28
So we can just rearrange our equation a little bit...
