persamaan kuadrar x^2 + 4px + 4 = 0 mempnyai akar x1 dan x2 jika x1x2 kuadrat 2 + x1kuadrat2 x2 = 32 maka nilai p

Answer 1

dik --> a = x² , b = 4px , c=4

peny :
x₁ + x₂ = -b/a = -4p/1 = -4p
x₁ . x₂ = c/a = 4/1 = 4

x₁x₂ + x₁x₂ = 32
x₁.x₂ ( x₂+x₁) = 32
     4 (-4p) = 32
         -16p = 32/16
              p = -2
