Question

Simplify:
9x2 - 4x – 3 = [?]
-
=
x=-2

Answer 1

Step-by-step explanation:

if x = -2

= 9x² - 4x - 3

= 9 ( -2)² - 4 ( -2 ) - 3 [ x = -2 ]

= 9 × 4 + 8 - 3

= 36 + 8 - 3

= 44 - 3

= 41

Answer 2

$\huge{\boxed{{ x = -2}}}$

$9x² - 4x - 3$

$↠ 9 (-2)² -4 (-2) - 3$

$↠ 9×4+8-3$

$↠ 36 + 8 -3$

$↠ 44-3$

$↠ 41$
