Answer:
Ss={}
Step-by-step explanation:
6x^2+1<or=0
6x^2<or=-1
x^2<or=-1/6
x<or=root-1/6
There is no number that satisfiey this equation
SS={}
Answer:
2 (x - 5)

Step-by-step explanation:
∠POR is congruent to ∠VOE because they are vertical angles
∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.
VO is congruent to OR which is given
Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem
So, PR is congruent to VE because corresponding parts of congruent triangles are congruent
Answer:
a = 3
b= -1
c = 5
X = (-b +- sqrt [b^2 - 4ac]) / 2a
X = (--1 +- sqrt (1 - 4*3 * 5)) / 2* 3
x = (1 += sqrt (1 -60)) / 6
x1 = (1 + sqrt (-59)) / 6
x2 = (1 - sqrt (-59)) / 6

Answer: x1=-2
x2=2
Step-by-step explanation:
5x²+4x-19=4x+1
5x²+4x-19-4x-1=0
5x²-20=0
5x²=20
x²=20/5
x²=4
x1=-√4=-2
x2=+√4=2
