Question

Find the roots of the given equation



$\sqrt{2x + 9} + x = 13$
​

Answer 1

Answer:

hey mate !

root 2x+3 multiply 3 + x =13

3 root 2x + x =13

3+x root 2x =13

x root 2x = 13-3

x root 2x = 10

hope it will help you. ✌️✌️

Answer 2

Answer:

x = 20, 8

Step-by-step explanation:

√(2x + 9) = 13 - x

(2x + 9) = (13-x)²

2x + 9 = 169 - 26x + x²

x² -28x + 160 = 0

Find two numbers such that their sum is 28 and product is 160. The only possible solution is 8,20.

(x - 20)(x - 8) = 0

x = 20,8
