4x2 – 5x - 1, find the value of
​

Answer 1

Answer:

8-5x

Step-by-step explanation:

4×2-5x-1

4×2=8- 5x-1

8×1- 5x

8-5x(ANS)

Answer 2

HERE IS YOUR ANSWER MATE....;

$= > 4x {}^{2} - 5x - 1 = 0$

$= > 4x {}^{2} - 4x -x - 1 = 0$

$= > 4x(x + 1) - 1(x + 1) = 0$

$= > (x + 1)(4x - 1) = 0$

$= > x = - 1$

$= > x = \frac{1}{4}$

HOPE IT'S HELPFUL....:-)
