Question

find the zeroes of polynomial p(x)=4x²-1

​

Answer 1

$\huge\bf\boxed{\boxed{\underline{\red{Answer!!}}}}$

$4x² - 1$

$4x² - 1 = 0$

$4x² = 0 - 1$

$4x² = 1$

$x² =$ $\frac{1}{4}$

$x =$ $\sqrt\frac{1}{4}$

$x =±$$\frac{1}{2}$

$\:So \:the \:two \:zero \:are$ $\frac{1}{2}$ , $\frac{-1}{2}$
