Question

check whether the following are quadratic equation x square-2x=(-2)(3-x)​

Answer 1

Answer:

X=-1.41

Step-by-step explanation:

X^2-2X=(-2)(3-X)

X^2-2X=-6+2X

X^2-2X-2X=-6

X^2-(2X)^2=6

X^2-4X^2=-6

3X^2=-6

X^2=-6/3

X^2=-2

X=-√2

X=-1.41

Answer 2

Answer:

x²-2x=(-2)(3-x)

x2-4x+6=0

- B ± √ B2-4AC

x = ————————

2A

In our case, A = 1

B = -4

C = 6

Accordingly, B2 - 4AC =

16 - 24 =

-8

Applying the quadratic formula :

4 ± √ -8

x = —————
