Convert to the product of multiplication<br>a^2-b^2-4b-4

kirill [66]

$a^2-b^2-4b-4$ in form of multiplication is $(a-b)(a+b)-4(b+1)$ .

<u>Step-by-step explanation:</u>

We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .

Here , we need to convert to the product of multiplication

a^2-b^2-4b-4 or , $a^2-b^2-4b-4$ :

⇒ $a^2-b^2-4b-4$

We know by identity that , $p^2-q^2 = (p-q)(p+q)$

⇒ $(a-b)(a+b)-4b-4$

Taking common term out as -4 :

⇒ $(a-b)(a+b)-4(b+1)$

Therefore , $a^2-b^2-4b-4$ in form of multiplication is $(a-b)(a+b)-4(b+1)$ .

Use a Pythagorean identity to rewrite the equation below using only the function sin θ. Then find the value of r if θ=30°,60°, a

zepelin [54]

$\bf sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)\\\\
-------------------------------\\\\
r=4sin(\theta )cos^2(\theta )\implies r=4sin(\theta )[1-sin^2(\theta )]
\\\\\\
r=4sin(\theta )-4sin^3(\theta )\qquad \qquad 
\begin{cases}
r=4sin(30^o)-4sin^3(30^o)\\
r=4sin(60^o)-4sin^3(60^o)\\
r=4sin(90^o)-4sin^3(90^o)
\end{cases}$

$\bf \begin{cases}
r=4\left( \frac{1}{2} \right)-4\left( \frac{1}{2} \right)^3\\\\
r=4\left( \frac{\sqrt{3}}{2} \right)-4\left( \frac{\sqrt{3}}{2} \right)^3\\\\
r=4(1)-4(1)^3
\end{cases}\implies 
\begin{cases}
r=2-\frac{1}{2}\\\\
r=2\sqrt{3}-\frac{3\sqrt{3}}{2}\\\\
r=4-4
\end{cases}\implies 
\begin{cases}
r=\frac{1}{2}\\\\
r=\frac{\sqrt{3}}{2}\\\\
r=0
\end{cases}$
