Question

2 y square + 9 Y + 10 is equal to zero solve by completing the square method​

Answer 1

Answer:

y= -2, -5/2

Step-by-step explanation:

2y²+9y+10=0

By completing the sqaure method:-

⇒y²+9y/2+5=0

⇒y²+ 2×9/4×y + (9/4)²-(9/4)²+5=0

⇒(y+9/4)²=81/16 - 5

⇒(y+9/4)²=1/16

⇒y+9/4=±1/4

⇒y = -9/4±1/4

So, y=-2 and y=-5/2
