Solve for x: (x+a)(x-b) = x^2 -1 How do I solve this ?

Sveta_85 [38]

You must factor.

$x^2-1=(x+1)(x-1)$

The factored form is equal to the assigned form.

$(x+1)(x-1)=(x+a)(x-b)$

Values a, b correspond to the factored 1, -1.

Value of x however remains unknown. But we can change that.

Given factored result,

$(x+1)(x-1)$

We can set expression equal to 0 then find such x that when added with number a or b results with 0.

$(x+1)(x-1)=0$

Hence x has 2 solutions.

$x+1=0\Rightarrow\boxed{x_1=-1} \\x-1=0\Rightarrow\boxed{x_2=1}$

Hope this helps.
