Algebra 2 help. Solving equations containing two radicals

Marysya12 [62]

These are 3 questions and 3 answers.

Question 1.

Answer: bot equations have the same potential solutions, but equation A may have extraneous solutions

Explanation:

1) Equation A

$\sqrt{x^2+3x-6}=\sqrt{x+2}\\ \\ x^2+3x-6=x+2\\ \\ x^2+2x-8=0\\ \\ (x+4)(x-2)=0\\ \\ x=-4 ; x =2$

Replace x = -4 in the right side of the equation:

$\sqrt{x+2} =\sqrt{-4+2} =\sqrt{-2}$

Which is not defined, so this is a extraneous solution.

2) Equation B.

Since it is a cube root, it is defined for any (negative, zero, and positive) values of x.

Question 2.

Answer: cubing both sides once.

Explanation:

$\sqrt[3]{5x-2} -\sqrt[3]{4x} =0\\ \\ \sqrt[3]{5x-2} =\sqrt[3]{4x}\\ \\ (\sqrt[3]{5x-2} )^3=(\sqrt[3]{4x})^3\\ \\ 5x-2=4x\\ \\ 5x-4x=2\\ \\ x=2$

3) Question 3.

Answer: c - 2 = 25 + c + 10√c

Explanation:

$\sqrt{c-2} -\sqrt{c} =5\\ \\ \\ \sqrt{c-2} =\sqrt{c} +5\\ \\ (\sqrt{c-2})^{2} =(\sqrt{c}+5)^2\\ \\ c-2=c+10\sqrt{c} +25\\ \\ c-2=25+c+10\sqrt{c}$

When is a *-m/n* a real number? *superscript

Aleksandr [31]

Since real numbers are closed with respect to division (i.e. the division between two real numbers is again a real number), the fraction $-\frac{m}{n}$ is a real number everytime both m and n are real numbers.

In other words, you can choose any real number m and any real number n, and their ratio will still be a real number.

Of course, you have to follow the only rule that you can't divide by zero, so the answer is more precisely

$m \in \mathbb{R},\quad n \in \mathbb{R}\setminus\{0\}$

An arithmetic sequence is represented by the recursive formula a1=17an=an−1−8 . What is the fourth term in the sequence? a4=−4 a

user100 [1]

Answer:

a₄ = - 15

Step-by-step explanation:

Using the recursive formula and a₁ = 17 , then

a₂ = a₁ - 8 = 17 - 8 = 9

a₃ = a₂ - 8 = 9 - 8 = 1

a₃ = a₂ - 8 = 1 - 8 = - 7

a₄ = a₃ - 8 = - 7 - 8 = - 15
