Question

Replace your expression for h2 in c2=h2 b2-2bx x2.

Answer 1

Answer:

c²=a²+b²-2bx

Step-by-step explanation:

Given,

h²=a²-x²

We need to plug this equation into

c²=h²+b²-2bx+x²

We can replace h² and we get

c²=a²-x²+b²-2bx+x²

Now， we can cancel the terms

c²=a²+b²-2bx

So we get after simplification as

c²=a²+b²-2bx
