MCQ
The zero of $3x + 2$ is:
A
$\frac23$
B
$\frac32$
✓
$-\frac23$
D
$\frac{-3}{2}$
✓
Answer
Correct option: C.
$-\frac23$
If $3x + 2 = 0,$ then
$3x = -2 ($Transposing $+2$ to $R.H.S.)$
$\Rightarrow\text{x}-\frac{2}{3}$
So, the zero of $3x + 2$ is $-\frac23.$ Note: A zero is that number, when put in place of the variable, makes the expression equal to zero.
Hence, the correct alternative is option $(c).$
