Find x, if f(x) = g(x) where f(x) = x4 + 2x2 , g(x) = 11x2 - Mathematics and Statistics

Find x, if f(x) = g(x) where f(x) = x⁴+ 2x² , g(x) = 11x²

योग

f(x) = x⁴ + 2x² , `"g"(x)` = 11x²f(x) = g(x)
∴ x⁴+ 2x² = 11x²∴ x⁴– 9x²= 0
∴ x² (x² – 9) = 0
∴ x = 0 or x²– 9 = 0
∴ x = 0 or x² = 9
∴ x = 0 or x = ± 3
