I believe it’s a circle because all of the others have points that can result in a positive and rations number
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
Am irrational number is a number that cannot be expressed as a fraction for any integers. numbers of the form,where is the logarithm, are irrational if and are integers, one of which has a prime factor which the other lacks. is irrational for rational
