Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x? O 1+ 213
0-17 19:
O 1+2 19
O 1+ 19;

Step-by-step explanation:

x² + 20 = 2x

x² − 2x + 20 = 0

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-2) ± √((-2)² − 4(1)(20)) ] / 2(1)

x = [ 2 ± √(4 − 80) ] / 2

x = [ 2 ± √(-76) ] / 2

x = [ 2 ± 2i√19 ] / 2

x = 1 ± i√19

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c
