This is an example of a factor pattern called the Difference of Two Squares.

$A^2-B^2=(A+B)(A-B)$

What is playing the role of A? What do you square to get $9x^2$ ? That would be $3x$ .

What is playing the role of B? What do you square to get 64? That would be 8.

Your expression factors as $(3x+8)(3x-8)$

A car is driving at the speed of 58 kilometers per hour. how much time will it take to drive for distance of 32 miles ?

quester [9]

well, we know that there are 1.609 kilometers in 1 mile, so 58 kilometers will be 58 ÷ 1.609 ≈ 36.05 miles.

we know the car is doing 36.05 miles in 1 hour, how long will it be for 32 miles?

$\bf \begin{array}{ccll} miles&hours\\ \cline{1-2} 36.05&1\\ 32&x \end{array}\implies \cfrac{36.05}{32}=\cfrac{1}{x}\implies 36.05x=32 \\\\\\ x=\cfrac{32}{36.05}\implies x\approx 0.8877\qquad \leftarrow \textit{53 minutes and about 16 seconds}$
