Question

esposta da equação por Bhaskara : x² +2x-35=0

Answer 1

$\boxed{\mathsf{\Delta=b^2-4ac}}$

2² -4 * 1 * -35

4 +140

144 = 12²

$\boxed{\mathsf{x=\frac{-b\pm\sqrt{\Delta}}{2a}}}}$

-(2) ± √12² /2

-1 ± 6

{5 , -7}

Answer 2

$x {}^{2} + 2x - 35 = 0$


a = 1

b = 2

c = - 35



∆ = 2^2 - 4 . 1 . (-35)

∆ = 4 + 140

∆ = 144

∆ =√144

∆ = 12



X ' = - 2 + 12 / 2

X ' = 10 / 2

X ' = 5


X " = - 2 - 12 / 2

X " = - 14 / 2

X " = - 7





S = { 5 , - 7 }
