Sebastian solved the radical equation y + 1 = but did not check his solution. (y + 1)2 = y2 + 2y + 1 = –2y – 3 y2 + 4y + 4 = 0 (
Softa [21]

Answer:

There are no true solutions to the equation.

Step-by-step explanation:

<u><em>The correct equation is</em></u>

y+1=\sqrt{-2y-3}

Solve for y

squared both sides

(y+1)^2=(-2y-3)

(y^2+2y+1)=(-2y-3)

y^2+2y+1+2y+3=0

y^2+4y+4=0

(y+2)(y+2)=0

y=-2

<em>Verify</em>

substitute the value of y in the original expression

-2+1=\sqrt{-2(-2)-3}

-1=1 ----> is not true

therefore

There are no true solutions to the equation.

Solve for x: −3|x − 3| = −6
Simora [160]

Answer:

x = 5                         x = 1

Step-by-step explanation:

−3|x − 3| = −6

Divide each side by -3

−3/-3|x − 3| = −6/-3

|x − 3| = 2

An absolute value is equal to a positive and negative solution

x-3 =2      and      x-3 = -2

Add 3 to each side

x-3+3 = 2+3            x-3+3 = -2+3

x = 5                         x = 1
