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

You must factor.

The factored form is equal to the assigned form.

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

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

Given factored result,

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

Hence x has 2 solutions.

Hope this helps.

Step-by-step explanation:

(x + a)(x - b) = x² - 1

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

By equality :

a = 1

b ÷ -1

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
