Question

a2-16a+16=0 solve this equation​

Answer 1

Answer :

= a² - 16a + 16 = 0

= a=$\dfrac{-\left(-16\right)±\sqrt{\left(-16\right)^{2}-4\times 16}}{2}$

=a=$\dfrac{-\left(-16\right)±\sqrt{256-64}}{2}$

=a=$\dfrac{-\left(-16\right)±\sqrt{192}}{2}$

=a=$\dfrac{-\left(-16\right)±8\sqrt{3}}{2}$

= a=$\dfrac{16±8\sqrt{3}}{2}$

=a=$\dfrac{8\sqrt{3}+16}{2}$

=a=$4\sqrt{3}+8$

=a=$\dfrac{16-8\sqrt{3}}{2}$

=a=$8-4\sqrt{3}$

The value of a is

• a=$4\sqrt{3}+8$
• a=$8-4\sqrt{3}$
