Question

resolvendo equaçoes da forma ax2²+b=0 (g) x²-100=0 (h) x²-81=0 (i) x²-196=0 (j) x²-900=0 (k) x²-36=0 (l) x²-121=0

Answer 1

Resposta:

(g) x²-100 = 0

    x²= 100

    x = $\sqrt{100}$

    x = 10

(h) x²-81 = 0

   x² = 81

   x = $\sqrt{81}$

   x = 9

(i) x²-196 = 0

   x² = 196

   x = $\sqrt{196}$

   x = 14

(j) x²-900 = 0

   x² = 900

   x = $\sqrt{900}$

   x = 30

(k) x²-36 = 0

    x² = 36

    x = $\sqrt{36}$

    x = 6

(l) x²-121 = 0

   x² = 121

   x = $\sqrt{121}$

   x = 11
