Question

find the zeroes of the polynomials p(x
$2x {} ^ {2 } +5x - 12$
​

Answer 1

Step-by-step explanation:

$\: \: \: \: 2 {x}^{2} + 5x - 12 = 0 \\ = > 2 {x}^{2} + 8x - 3x - 12 = 0 \\ = > 2x(x + 4) - 3(x + 4) = 0 \\ = > (x + 4)(2x - 3) = 0$

x+4=0. |. 2x-3. =0

=>. x=-4. |. => 2x=3

|. =>. x=3/2

x=. -4 and 3/2.
