solve pliiiiiz

Answer 1

Answer:

appying middle term split

take factors common

equate each with zero

Answer 2

Answer:

y1 = -4, y2 = 12

Step-by-step explanation:

¼y² - 2y - 12 = 0

Multiply all the terms by 4 to rid of the denominator in the first term...

y² - 8y - 48 = 0

Factorising,

y² + 4y - 12y - 48 = 0

y(y+4) - 12(y+4) = 0

(y+4)(y-12) = 0
