Hey! First of all, you can express x squared as x^2.
Secondly, the problem! I'm assuming you're asking for the values of x - if you're asking what the equation is, it's a quadratic equation, or a second-degree polynomial. Solving for x, this equation can be factored as (x-4)(x+1)=0. Because either of these two terms being zero will make the whole equation zero, we can have x-4=0, in which case x=4, or x+1=0, in which case x=-1. Therefore, x is either 4 or -1
Answer:
x = 28
Step-by-step explanation:
The ratios of corresponding sides are equal, that is
= 
( cross- multiply )
8(x - 7) = 168 ( divide both sides by 8 )
x - 7 = 21 ( add 7 to both sides )
x = 28
The answer is 8. I explain it to you?
