$\implies {\blue {\boxed {\boxed {\purple {\sf {20}}}}}}$

$\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:EXPLANATION:}}}$

$= ( {2}^{2} + {4}^{2} )$

$= [(2 \times 2) + (4 \times 4)]$

$= (4 + 16)$

$= 20$

3. Given this quadratic equation, 2x2 - x - 28 = 0,

JulijaS [17]

Answer:

a) (2x+7)(x-4)

b) x = -7/2 and x = 4

Step-by-step explanation:

a) (2x ?)(x ?)

set up the above and considered factors of 28 that, when paired with 2, would give me -1x and -28 → (1·28, 2·14, 4·7)

after trial-and-error, found that 4 and 7 worked (used un-FOIL)

b) 2x + 7 = 0

2x = -7

x = -7/2

*********

x-4 = 0

x = 4
