⫷❥ᴀ᭄n §₩ΣR⫸

Step-by-step explanation:

☆Equation=>8y^2-6y-5

=>8y^2-6y-5

=>8y^2+4y-10y-5 (Middle term splitting).

=>4y(2y+1)-10(2y+1)

=>(4y-10)(2y+1)

☞So from here, x=10/4=5/2 and x=-1/2.

HOPE IT HELPS.

Answer 2

Answer:

By splitting the middle term

Step-by-step explanation:

$8y {}^{2} - 6y - 5 = 0 \\ 8 {y}^{2} + 4y - 10y - 5 = 0 \\ 4y(2y + 1) - 5(2y + 1) = 0 \\ (4y - 5)(2y + 1)$
