1) solve the qaudractic eqaution 2x^2 +bx +3=0

2) describe using algebra and words how the nature/ number of roots of the eqaution of Q1 change as b varies, clearly identifying the ranges of the values of b which lead to different types of roots

3) pick a value of b which leads to complex roots and solve 2x^2 + bx +3=0 to confirm this

4) Do the partail fractions questions, it would help me understand if u could do one using the cover up rule, one using substitution method, one using comparing the coeffiecient

a) x-2/((2x+5)(x-6)

b) x^2 -2/((2x+5)(x-6))

c) (x-2)^2/((2x+5)^2(x-6)

d) (x-2)^2/(((2x+5)(x-6)(x+1)))
