Question

18. (X - 5)2 – (x + 2)2 = -2​

Answer 1

Step-by-step explanation:

${(x - 5)}^{2} - {(x + 2)}^{2} = - 2$

${x}^{2} + 25 - 10x - ( {x}^{2} + 4 + 8x) = - 2$

${x}^{2} + 25 - 10x - {x}^{2} - 4 - 8x = - 2$

$21 - 18x = - 2$

$- 18x = - 2 - 21$

$- 18x = - 23$

$x = \frac{ 23}{18}$

Answer 2

Answer:

x = 23/14 (please mark me as Brainliest and follow me)

Step-by-step explanation:

(x-5) ^2-(x+2)^2 = -2

x^2+25-10x-x^2-4-4x = -2

-14x+21 = -2

-14x = -23

x = 23/14
