Question

fórmula de bhaskara valores de a, b, c . a) 3x=-x^+1 b) x^=1 c) (x-5).(2x+1)=0 d)4x.(x+2)=0 f)10=x^-9x

Answer 1

a) 3x = -x^2 + 1
    x^2 + 3x - 1 = 0

a = 1
b = 3
c = -1

b) x^2 = 1
    x^2 - 1 = 0

a = 1
b = 0
c = -1

c) 2x^2 + x - 10x - 5 = 0
    2x^2 - 9x - 5 = 0

a = 2
b = -9
c = -5

d) 4x^2 + 8x = 0

a = 4
b = 8
c = 0

f) 10 = x^2 - 9x
x^2 - 9x - 10 = 0

a = 1
b = -9
c = -10
