Final answer:
To find the zero of the function 5x^2+3=83, subtract 83 from both sides and solve for x using square roots.
Step-by-step explanation:
To find the zero of the function 5x^2+3=83, we need to first rearrange the equation by subtracting 83 from both sides, giving us 5x^2 = 80. Next, we divide both sides of the equation by 5, resulting in x^2 = 16. To find the value of x, we take the square root of both sides, giving us x = ±4. So, the zeros of the function are x = -4 and x = 4.
