You would distribute:

So, the answer would be 15a^2-25ab+6ab-10b^2

Then we simplify:

15a^2-19ab-10b^2

I hope this helps!

x = 4 $\sqrt{3}$

Step-by-step explanation:

Given a tangent and a secant from an external point to a circle.

Then the square of the tangent is equal to the product of the secant's external part and the entire secant , that is

x² = 4(4 + 8) = 4 × 12 = 48 ( take square root of both sides )

x = $\sqrt{48}$ = $\sqrt{16(3)}$ = 4 $\sqrt{3}$
