How would you find the zero of f (x)=16x^4 - 9x^2

krok68 [10]

$f (x) = 16x ^ 4 - 9x ^ 2 \\ \\16x ^ 4 - 9x ^ 2=0\\ \\x^2(16x^2-9)=0 \\ \\x^2 =0 \ \ or \ \ 16x^2-9=0\\ \\ x=0 \ \ or \ \ (4x-3)(4x+3)=0\\ \\ x=0 \ \ or \ \ 4x-3=0 \ \ or \ \ 4x+3 =0\\ \\x=0 \ \ or \ \ 4x=3 \ \ / :4 \ \ or \ \ 4x=-3\ \ / :4 \\ \\ x=0 \ \ or \ \ x=\frac{3}{4} \ \ or \ \ x=-\frac{3}{4}$

X^3 - 8 = x - 2 Solve the equation for all values of x

kirill [66]

X³-8=x-2: Original equation.
x³-x-6=0: Subtract x and add 2 to both sides.
(x-2)(x²+2x+3): Factor the equation
x-2=0; x²+2x+3=0: Separate the expressions into equations
x=2: Add 2 to both sides
x²+2x+3=0: Quadratic Formula
x= 2, -2+√-8,-2-√-8
 2 2
