Question

$2x {}^{2} + 5x + 2$
​

Answer 1

Answer:

x = -2           ;            x = -1/2

Step-by-step explanation:

2x² + 5x + 2 = 0

Using splitting the middle term,

2x² + 4x + x + 2 = 0

2x(x + 2) + 1(x + 2) = 0

(x + 2)(2x + 1) = 0

x + 2 = 0              ;              2x + 1 = 0

x = -2                                  2x = -1

                                          x = -1/2

Answer 2

$\huge\bf{Question}$

$2x {}^{2} + 5x + 2$

$\huge\bf\red{Solution}$

$2x {}^{2} + 5x + 2$

$2 {x}^{2} + 4x + 1x + 2$

$2x(x + 2) + 1(x + 2)$

$(2x + 1)(x + 2)$
