Question

4xsquare+8x-3=0 then x=1/2y to find y​

Answer 1

Answer:

-13/4=Y

Step-by-step explanation:

4^2 +8x-3 =0

16-3+8x=0

8x=-13

X=-13/8 (eq 1)

Since x=1/2Y (given)

-13/8= 1/2Y (comparing given and eq 1)

-13/8×2=Y

-13/4=Y

Answer 2

Step-by-step explanation:

put the value of x in the given equation

after putting value of x

1/y^2+4/y-3

taking lcm

lcm is y^2

-3y^2+4y+1=0

taking - common

3y^2-4y-1=0

use formula of quadratic equations

b^2-4ac

after that use formula

a= -b+-√d/2a
