Question

(x - 5)^2-(x+2)^2 = -2​

Answer 1

Answer:

Yes it is right you have written write Good

Answer 2

Answer:

Given,

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

Expand them,

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

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

$-14x + 21 = -2\\-14x = -2 - 21\\-14x = -19\\14x = 19 \\x = \frac{19}{14}$
