Question

RESOLVA A EQUAÇAO DO 2 GRAU X +5X -6=0

Answer 1

delta=

${b}^{2} - 4ac \\ {5}^{2} - 4 \times 1 \times ( - 6) \\ 25 + 24 \\ delta = 49$

Answer 2

A = 1 B = 5 C = -6

Δ = B2 - 4.A.C

Δ = 52 - 4.1.(-6)

Δ = 25 + 24

Δ = 49

X = -B +- √Δ / 2.A

X = -5 +- √49 / 2.1

X = -5 +- 7 / 2

X| = -5 + 7 / 2

X| = 2 / 2

X| = 1

X|| = -5 - 7 / 2

X|| = -12 / 2

X|| = -6
