a=___; b=___; c=___

b)5x^2 -2x +2=0

a=___;b=___;c=___

c)3x^2+x+1=0

a=___;b=___;c=___

d)3x^2 -2x-5=0

a=___;b=___;c=___

e)-4x^2 +5x-1=0

a=___;b=___;c=____

f)3x^2 -5x-1=0

a=___;b=___;c=___​

Answer 1

a) x^2+3x-12=0

a = 1

b = 3

c = -12

b) 5x^2 -2x +2=0

a = 5

b = -2

c = 2

c) 3x^2+x+1=0

a = 3

b = 1

c = 1

d) 3x^2 -2x-5=0

a = 3

b = -2

c = -5

e) -4x^2 +5x-1=0

a = -4

b = 5

c = -1

f) 3x^2 -5x-1=0

a = 3

b = -5

c = -1
