Question

trigonometry std 10 y+2×-19=0​

Answer 1

Answer:

Solve : y2-19 = 0

Add 19 to both sides of the equation :

y2 = 19

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:

y = ± √ 19

The equation has two real solutions

These solutions are y = ± √19 = ± 4.3589

Two solutions were found :

y = ± √19 = ± 4.3589
