Question

solve 7 Y is equals to minus 3 y square - 4​

Answer 1

$\huge\bf\mathbb\red{HeyThere!}$

$7 {y}= - 3 {y}^{2} - 4$

$- 3 {y}^{2} - 7y - 4 = 0$

$3 {y}^{2} + 7y + 4 = 0$

$3 {y}^{2} + 3y + 4y + 4 = 0$

$3y(y + 1) + 4(y + 1)$

$(3y + 4)(y + 1)$

Answer 2

Answer:

Y=-1

Step-by-step explanation:

7y=-3y^2-4

-3y^2-7y-4=0

-3y^2-4y-3y-4=0

y(-3y-4)+1(-3y-4)=0

(y+1) (-3y-4) = 0

y=-1 or y= 4/3.......
