Q. Find the zeros of the function. Enter the solutions from least to greatest.\newlinef(x)=5x220lesser x=greater x=\begin{array}{l} f(x)=5x^{2}-20 \text{lesser } x=\square \text{greater } x=\square \end{array}
  1. Find zeros of the function: Set the function equal to zero to find its zeros.\newlinef(x)=5x220=0f(x) = 5x^2 - 20 = 0
  2. Factor out common factor: Factor out the common factor of 55 from the quadratic equation.5(x24)=05(x^2 - 4) = 0
  3. Apply zero product property: Apply the zero product property, which states that if a product of factors equals 00, then at least one of the factors must be 00.\newlinex24=0x^2 - 4 = 0
  4. Factor the difference of squares: Factor the difference of squares. (x2)(x+2)=0(x - 2)(x + 2) = 0
  5. Solve for x in each factor: Set each factor equal to zero and solve for x.\newlinex2=0x - 2 = 0 or x+2=0x + 2 = 0
  6. Solve for x in each factor: Set each factor equal to zero and solve for x. \newlinex2=0x - 2 = 0 or x+2=0x + 2 = 0 Solve the first equation for x. \newlinex2=0x - 2 = 0 \newlinex=2x = 2
  7. Solve for x in each factor: Set each factor equal to zero and solve for x. \newlinex2=0x - 2 = 0 or x+2=0x + 2 = 0 Solve the first equation for x. \newlinex2=0x - 2 = 0 \newlinex=2x = 2 Solve the second equation for x. \newlinex+2=0x + 2 = 0 \newlinex=2x = -2
