I need help with my algebra 2. I also want to know how to solve this.
Lisa [10]

Add 1 to both sides:

\sqrt{x+3} = x+1

In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that

x+1 \geq 0 \iff x \geq -1

Under this assumption, we square both sides and we have

x+3 = (x+1)^2 \iff x+3 = x^2+2x+1 \iff x^2+x-2 = 0

The solutions to this equation are

x = -2,\ x=1

But since we can only accept solutions greater than -1, we discard x=-2 and accept x=1.

In fact, we have

x=-2 \implies \sqrt{-2+3}-1=0\neq -2

and

x=1 \implies \sqrt{4}-1=1

which is the only solution.

To solve 493x = 3432x 1, write each side of the equation in terms of base.
iVinArrow [24]

The solution of the equation in terms of the base is \rm x = \dfrac{-1}{2939}\\\\.

Given that

Equation; \rm 493x= 3432x+1

We have to find

The solution of the equation in terms of base.

According to the question

To determine the solution of the equation following all the steps given below.

Equation; \rm 493x= 3432x+1

Then,

\rm 493x= 3432x+1\\\\493x-3432x=1\\\\-2939x=1\\\\x = \dfrac{-1}{2939}\\\\

Hence, the solution of the equation in terms of the base is \rm x = \dfrac{-1}{2939}\\\\.
