Question

Which expression is a factor of 12x2 + 29x – 8? x – 8 2x – 1 3x + 8 4x + 1

Answer 1

Heyy Dear ❤
Here is u r Ans ➡

$= 12x2 + 29x - 8x - 82x - 13x + 84x + 1$

$= 24 x - 74x + 84 + 1$

$= 24x - 74x + 85$

$= 24x - 74x + 85 \\ = - 50x + 85$
$= - 5(10x - 17)$

Hope This Helps u ☺.

Answer 2

Answer:

3x + 8 is our desired factor.

Step-by-step explanation:

Our given quadratic expression is

12x² + 29x - 8 =0

Now, let us factorize it in order to find the desired factor

12x² + 32x -3x - 8 =0

taking commons

4x (3x + 8) -1 (3x + 8) = 0

taking common again

(3x + 8)(4x - 1) = 0

So, as we can see that 3x + 8 is factor of our expression.

Therefore, Option c is our correct answer
