Question

Find value of Q in Z²+3Z-Q =3 for Z=2
plss help fast​

Answer 1

Step-by-step explanation:

as we know that the value of z=2

so we can frame the equation like this

z^2+3z-Q=3

now represent the values

2^2+3*2-Q=3

now solve it

4+6-q=3

10-q=3

transpose 10 to right side

-q=10-3

-q=7

so the value is 7.

now we can check it

4+6-7=3

it's correct...

I am just in class 8th.If you think my answer is correct

then thank you for supporting

Answer 2

Answer:

$q = - 7$

Step-by-step explanation:

${z}^{2} + 3z - q = 3 \\ z = 2 \\ {2}^{2} + 3 \times 2 - q = 3 \\ 4 + 6 - q = 3 \\ 10 - q = 3 \\ q = 3 - 10 \\ q = - 7$
