Misaka solved the radical equation x – 3 = square root of 4x-7 but did not check her solutions. (x – 3)2 = square root of 4x-7^2

Minchanka [31]

Answer:

x=8 is a true solution of the radical equation

Step-by-step explanation:

we have

$x-3=\sqrt{4x-7}$

Solve for x

squared both sides

$(x-3)^{2}=4x-7\\\\x^{2}-6x+9=4x-7\\\\ x^{2}-10x+16=0$

Convert to factored form

$x^{2}-10x+16=(x-2)(x-8)$

The solutions are x=2 and x=8

Verify the solutions

For x=2

Substitute in the original equation

$2-3=\sqrt{4(2)-7}$

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

therefore

x=2 is not a true solution of the radical equation

For x=8

Substitute in the original equation

$8-3=\sqrt{4(8)-7}$

$5=5$ ----> is true

therefore

x=8 is a true solution of the radical equation
