Hi. This is a test When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$ $(y+\sqrt z)^{-1}$ $$(y+\sqrt z)^{-1}$$ $$\frac 2 3$$ This is a test of using MathJax in Blogger Note that enclosing math in single $'s does not work in the default setting for MathJax. However, you may use "\(\backslash(\)" and "\(\backslash)\)" for inline math and double dollar signs or "\(\backslash[\)" and "\(\backslash]\)" for displayed math. Examples: $(y+\sqrt z)^{-1}$ and \( \sin^2 x^2 \). And, a displayed equation is: $$\frac 2 3$$ What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
