What is the factored form of the expression? d^2 = 36d + 324

(x-43.45)(x+7.45)=0.

Step-by-step explanation:

We have the quadratic equation i.e.

Now, the roots of the quadratic equation are given by

So, from the given equation, we have,

a = 1, b =-36 , c = -324.

Substituting the values in , we get,

i.e.

i.e.

i.e.

i.e.  and i.e.

i.e.  and i.e.

i.e. x = 43.45 and x = -7.45

Hence, the factored form of the given expression will be (x-43.45)(x+7.45)=0.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
