Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x? -1 IN
-10V21

1+2 V19;
1+ 19/

Step-by-step explanation:

Solve using quadratic formula

We start by representing the above equation property

Subtract 2x from both sides

Given a quadratic equation of the form

The quadratic formula is as follows;

Where a = 1, b = -2 and c = 20

Factorize -76

Split the square root

Square root of 4 is 2

Split Fraction

The expression can not be further simplified;

Hence,

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
