Question

In a right triangle the hypotenuse is x+6 and the other sides are x and 8.
Try to find x using the pythagorean theorem.

Answer 1

do you know the theorem?

Answer 2

a^2=b^2+c^2.

Answer 3

The problem is the x+6.

Answer 4

yes. where in this case a is the hypotenuse.

(x+6)^2 = x^2 + 8^2


to expand (x+6)^2, you can use FOIL, which is an acronym which helps you multiply (x+6)(x+6).

With habit, you'll see that (a+b)^2 is always a^2 + 2ab + b^2

so you can open it right away to x^2 + 12x + 36

Answer 5

Thank you.
