Question 4 Part B (2 points): In part A you factored f(x) = 9m2 + 3m - 2. What are the x intercepts of this function? SELECT ALL THAT APPLY.

A.
m = -1/3

B.
m = 1/3

C.
m = -2/3

D.
m = 2/3

E.
m = 3

F.
m = -3

G.
m = 6

H.
m = -6

Answer 1

We need zeros

$\\ \rm\Rrightarrow 9m^2+3m-2=0$

$\\ \rm\Rrightarrow 9m^2-3m+6m-2=0$

$\\ \rm\Rrightarrow 3m(3m-1)-2(3m-1)=0$

$\\ \rm\Rrightarrow (3m-2)(3m-1)=0$

• m=2/3
• mm=1/3
