Question

5m²+5m-1=0 by using formula method

Answer 1

5m2+5m-1=0
a=5, b=5 & c= -1

D=b2-4ac
= (5)^2 - 4×5×-1
= 25 + 20
= 45
Therefore, D us greater than
0
Therefore roots are real and
distinct

X = -b _+ √D/2a
Taking positive(+) sign

X= -5 + √45/2×5
= -5 + √45/10
= -√45/2

Taking negative(-)sign
X = -5 -√45/2×5
= -5 -√45/10
= √45/2
