Full solution

Q. F(x)=3x216+21F(x)=3x^2-16+21 find the zeros of the function
  1. Write Function and Coefficients: Write down the given function and identify the coefficients.\newlineThe given function is F(x)=3x216x+21F(x) = 3x^2 - 16x + 21. The coefficients are a=3a = 3, b=16b = -16, and c=21c = 21.
  2. Find Zeros: Set the function equal to zero to find the zeros. 0=3x216x+210 = 3x^2 - 16x + 21
  3. Factor Quadratic Equation: Factor the quadratic equation, if possible.\newlineTo factor, we look for two numbers that multiply to aca*c (321=633*21 = 63) and add to bb (16-16).\newlineThe numbers that satisfy this are 9-9 and 7-7 because 9×7=63-9 \times -7 = 63 and 9+7=16-9 + -7 = -16.
  4. Write Factored Form: Write the factored form of the equation.\newline0=3(x7)(x3)0 = 3(x - 7)(x - 3)
  5. Solve for x: Set each factor equal to zero and solve for x.\newlinex7=0x - 7 = 0 or x3=0x - 3 = 0\newlinex=7x = 7 or x=3x = 3
