Answer 1

Answer:

2 a b = m

Step-by-step explanation:

Answer 2

Answer:

x=3.732           or    x=0.268

Step-by-step explanation:

given equation:

m²-4m+1=0

since the equation cannot be factorised we shall use the formula

(-b±√b²-4ac)/2a

here, a=1,  b =-4 , c=1

= (-1* -4±√-4²-4*1*1)/2*1

=(+4 ±√16-4)/2

=(4±√12)/2

=4± 3.464/2

=>x=4+ 3.464/2   or   x=4- 3.464/2

=>x=7.464/2        or   x=1.464/2

=>x=3.732           or    x=0.268

Hope it helps !!
