Question

pls help me in this (options are given for you)

Answer 1

$\frac{ - 4a}{2} + 1 = 0 \\ \frac{ - 4a}{2} = - 1 \\ - 4a = - 1 \times 2 \\ - 4a = - 2 \\ a = \frac{ - 2}{ - 4} \\ a = \frac{1}{2}$

Answer 2

Answer:

-4a/2 +1 = 0

-4a/2=-1

-4a=-2

4a=2

a= 2/4

a=1/2.

so the answer is ...a=1/2
