Question

if one root of the equation X square - 5 x + K equal to zero is equal to 4 find the value of k and the other root​

Answer 1

$HEYA \: \\ \\ x {}^{2} - 5x + k = 0 \\ x = 4 \\ becoz \: it \: is \: given \: that \: one \: root \: is \: 4\\ \\ (4) {}^{2} - 5(4) + k = 0 \\ \\ 16 - 20 = k \\ \\ k = 4 \\ \\ x {}^{2} - 5x + 4 = 0 \\ let \: the \: other \: root \: of \: this \: equation \: is \: \alpha \\ \\ \alpha + 4 = 5 \\ \\ \alpha = 1 \\ \\ so \: the \: other \: root \: is \: 1$
