3) 121 - x2 = 0
4) 3x2 + 16 = 0
5) 16x2 + 6 = 0​

Answer 1

RESPUESTA:

[tex]121 - x2 = 0\\ 121 -2x =0\\-2x=-121\\x=-121/-2\\x=121/2\\x =60.5[/tex]

RPTA = "x"  →  60.5

[tex]3\cdot x2 + 16 = 0[/tex]

[tex]6x+16=0\\6x=0-16\\6x=-16\\x=\frac{-16}{6}\\Simplificar\\x=-\frac{8}{3}[/tex]

RPTA = "x" → 16/6

[tex]16x\cdot \:2\:+\:6\:=0\\32x+6=0\\32x=0-6\\32x=-6\\x=-\frac{-6}{32}\\Simplifico\\x=-\frac{3}{16}[/tex]

RPTA = "x" → [tex]-\frac{3}{16}[/tex]
