Question

Miguel correctly factored 4x2 - 6x - 4 as (x - 2)(4x + 2)

He then claimed that the zeros of that quadratic function f(x) = 4x2 - 6x - 4 are x = -2 and x = 12

PART A: Explain Miguel's error.

PART B: Correct Miguel's error.

Answer 1

Answer:

Step-by-step explanation:

hello :

4x2 - 6x - 4 =0  means : (x - 2)(4x + 2)=0

x-2=0 or 4x+2=0

x=2 or x=-1/12 no 12
