Question

find the zeroes of the quadratic polynomial f of x equal to 4x square- 5x -1​

Answer 1

$\huge{\bold{ Solution}} \\ \\ 4 {x}^{2} - 5x + 1 = 0 \\ \\ 4 {x}^{2} -x - 4x + 1 = 0 \\ \\ x(4x - 1) - 1(4x - 1) = 0 \\ \\ (x - 1)(4x - 1) = 0 \\ \\ x = 1 \\ \\ 4x = 1 \\ x = \frac{1}{4} \\ \\ The \: Zeroes \: of \: equ. \: is \: 1 \: and \: \frac{1}{4}$
