Question

Quadratic equations

4x2 - 16 = 0

2x2 = 16

x2 + 5 = 0

x2 + 4x - 6 = 0 (Solve by completing the square)

x2 - 25 = 0

3x2 = -9x

2x2 - 4x + 1 = 0

3x2 + 2x = 7

x2 + 8x + 9 = -7

Answer 1

which one u want to solve?

Answer 2

do u want to know how to complete the square?

Answer 3

x2 + 4x - 6 = 0
x2 + 4x = 6
x2 + 4x +4 = 6 +4
(x+2)(x+2)=10
(x+2)^2=10
x=\[sqrt10 - 2\]

Answer 4

look up youtube video on complete the square if u dont know already

Answer 5

there all seperate equations

Answer 6

and?
