8y² – 9y + 1 = 0 solution for this problem

Answer»

$y = \frac{ - 1}{8} \: or \: y = - 1$

Step-by-step EXPLANATION:

$8 {y}^{2} - 9y + 1 = 0$

$8 {y}^{2} - (8 + 1)y + 1 = 0$

$8 {y}^{2} - 8y - 1y + 1 = 0$

$8y(y + 1) + 1(y + 1) = 0$

$(y + 1)(8y + 1) = 0$

$y + 1 = 0 \: or \: 8y + 1 = 0$

$y = - 1 \: or \: y = \frac{ - 1}{8}$

$i\:hope\:it\:will\:help\:u☺☺$
