Question

exercițiul 1 si 2 va rogg

Answer 1

poftim primul exercitiu si al doilea

Answer 2

ex1)4x+3=-1⇒4x=-3-1⇒4x=-4⇒x=-4/4⇒x=-1
x²=1⇒x²-1=0⇒x=+-1
t²+2=6⇒t²+2-6=0⇒t²-4=0⇒t=-+2
y²+4=0⇒y=-+2

2)5x+05.=5.5⇒5x=5.5-0.5⇒5x=5⇒x=5/5⇒x=1
b)(x-1)(x+1)=o⇒x²-x+x-1=0⇒x²-1=0⇒x=+-1
c)t+1/t-2=-2⇒t+1=-2(t-2)=t+1=-2t+4⇒t+2t=4-1⇒3t=3⇒t=3/3⇒t=1
d)t²-1=0⇒t=-+1
e)1/x-1=0⇒1=(x-1)×0⇒1=0⇒1
