Question

$\sqrt{2x + 9 } - \sqrt{x + 1 } = \sqrt{x - 4}$
​

Answer 1

Answer:

x=16

x=14

Step-by-step explanation:

Move the term with the radical to the right hand side:

2x+4=9√x

square both sides and collect like terms:

81x=4x2+16x+16

collect and equate to 0:

4x2−65x+16=0

Factor:

(4x−1)(x−16)=0

solution: x=16,x=14
