All you have to do here is add 209 to both sides to get -8x² - 9x + 209 = 0
From there I'm sure you can work it out :)

In a circle with center P and radius 10cm. If one of the chord is of length 12 cm.

juin [17]

Look at the attachment

The line bisects the cord which we have to find

Length of chord=12cm
Half of the cord=12/2=6cm
Radius=10cm

Its a right angle triangle

using Pythagorean theorem

$\boxed{\sf P^2=H^2-B^2}$

$\\ \Large\sf\longmapsto P=\sqrt{H^2-B^2}$

$\\ \Large\sf\longmapsto P=\sqrt{10^2-6^2}$

$\\ \Large\sf\longmapsto P=\sqrt{100-36}$

$\\ \Large\sf\longmapsto P=\sqrt{64}$

$\\ \Large\sf\longmapsto P=8cm$

Distance of the chord from centre is 8cm.
