# 32 + 48x^2 + 2x^4 = 136 watch

32 + 48x^2 + 2x^4 = 136

Thanks.
2. let y = x2

so 32 + 48y + 2y2 = 136

that better?

Treat it as a quadratic, but instead of it being it's going to be

Love you
5. 32 + 48x^2 + 2x^4 = 136 (divide by 2)
16 + 24x^2 + x^4 = 68 (Take away 68 from both sides)
x^4 + 24x^2 - 52 = 0 (Quadratic Equation)
(x^2 + 26) (x^2 - 2) = 0

x^2 = -26 or X^2 = 2

Therefore x = square root of 2
