Answer: The solution is two distinct real zeros.

Step-by-step explanation:

Subtract 6 from both sides:

$x^2-3x-6=6-6\\x^2-3x-6=0$

Calculate the discriminant:

$D=b^2-4ac$

Where:

a=1

b=-3

c=-6

Then:

$D=(-3)^2-4(1)(-6)=33$

By definition, when $D>0$ the solution is two distinct real zeros.

Answer:

$(\frac{dy}{dt})^2=sin^2t$

Step-by-step explanation:

$y=cost$

DE : $(\frac{dy}{dt})^2=1-y^2$

If y is a solution of given DE then it satisfied the DE.

Differentiate w.r.t t

$\frac{dy}{dt}=-sint$

Using the formula

$\frac{d(cosx)}{dx}=-sinx$

LHS: $(\frac{dy}{dt})^2=(-sint)^2=sin^2t$

RHS

$1-y^2=1-cos^2t=sin^2t$

By using the formula

$sin^2t=1-cos^2t$

LHS=RHs

Hence, y is a solution of given DE

$(\frac{dy}{dt})^2=sin^2t$
