Question

if x+9,x-6,4are the first three element of g.p then xis​

Answer 1

$\huge\underline\mathfrak\purple{Answer}$

x + 9 , x - 6 , 4 are in GP

so

( x - 6 )² = 4 ( x + 9 )

x² + 36 - 12x = 4x + 36

x² = 16x

x = 16

Thanks! ☺

Answer 2

Step-by-step explanation:

(x-6)^2=4(x+9)

x^2+36-12x=4x+36

x^2-16x=0

x=0;16
