Question

What do I type in the yellow boxes?

Answer 1

Answer:

x=-2

Step-by-step explanation:

x= -b/2a

b=4

a=1

x=-4/2*1

x=-4/2

x=-2

Answer 2

Given equation ⤵️

$\sf \longrightarrow \: y = {1x}^{2} + 4x + 2$

Where,

• a = 1
• b = 4
• c = 2

Put the values in the formula

$\tt \dashrightarrow \: x = \frac{ - b}{2 \times a}$

$\sf \longrightarrow \: x = { \frac{ - 4}{2 \times 1}}$

$\sf \longrightarrow \: x = \frac{ - 4}{2}$

$\sf \longrightarrow \: x = - 2$
