It is very interesting and magnificent.

Stop and solve

@virtualgerald 👍🏻

@Math_World_ == 9.375

@naha3030900 There is one more root

@Math_World_ 3

Stop and solve

@Math_World_ 5𝒙² - 13𝒙 - 6 = 0 (5𝒙 + 2)(𝒙 - 3) = 0 𝒙 = - 2/5 𝐎𝐫 𝒙 = 3

@EOdileke 👍🏻👍🏻

@Math_World_ 5x^2-13x-6=0 5x^2-15x+2x-6=0 5x(x-3)+2(x-3)=0 (x-3)(5x+2)=0 x=3 or x=-2/5 x=-2/5, 3

@musafir_hidup 👍🏻

@Math_World_ 9.375

@vaynkvink 👍🏻👍🏻

@Math_World_ {-2/5,3}

@Sparrow_109 Yes 👍🏻

@Math_World_ 9.375 is the right answer 😌

@Math_World_ Lets assume radius to be r So r^2=(12-r)^2 +(9)^2 r^2= 144-24r+r^2+81 We cancel r^2 from both side 144-24r+81=0 24r=225 R=225/24 Radius = 9.375

@Ptiki 👏🏻👏🏻

@Math_World_ r^2 = 9^2 + (12-r)^2 (a-b)^2 = a^2 + 2ab + b^2 r^2 = 81 + 144 - 24r + r^2 r^2 on both sides cancels, move -24r to other side (becomes +24r) 24r = 225 r = 225/24 = 9,375

@Math_World_ 9.375

@Nought_G Thanks 🎉

@Math_World_ 9^2 + (12-r)^2 = r^2 81 + (144 - 24r + r^2) = r^2 225 - 24r + r^2 = r^2 225 - 24r = 0 24r = 225 r = 225/24 = 75/8 = 9.375cm This was fun

@NongPrachya 👏🏻👏🏻

@Math_World_ Using the intersecting chords theorem ; (12)(2r-12)=(9)(9) r = 75/8

@Rodri_Fdez_848 👎🏻

@Math_World_ Radio = 7.5 cm

@IluveAtar 👏🏻👏🏻

@Math_World_ (12+x)^2 = x^2 + 9^2 + 12^2 + 9^2 12^2 +x^2 + 24x = x^2 + 9^2 + 12^2 + 9^2 24x = 2* 9^2 x = 27/4 R = (12+x)/2=6+27/8=75/8
