Question

What are the solution(s) to the quadratic equation 9x2 = 4?

Answer 1

$Given \: quadratic \: eqution : \\9x^{2} = 4$

$\implies x^{2} = \frac{4}{9}$

$\implies x = ± \sqrt{\frac{4}{9}}\\= ± \sqrt{\frac{2^{2}}{3^{2}}}\\=± \frac{2}{3}$

Therefore.,

$-\frac{2}{3} , \:\frac{2}{3} \:are \: two \: roots \\of \: given \: quadratic \: eqution.$
