Solution

Let's solve the equation by factoring step by step.

Part 1: Rewrite the equation in factored form

The given equation is: x2=5x+14x^2 = 5x + 14

First, let's move all terms to one side of the equation to set it equal to zero: x25x14=0x^2 - 5x - 14 = 0

Next, we need to factor this quadratic equation. We are looking for two numbers that multiply to 14-14 (the constant term) and add to 5-5 (the coefficient of the xx term). These numbers are 7-7 and 22, so we can factor the quadratic as: (x7)(x+2)=0(x - 7)(x + 2) = 0

Part 2: The solution set

To find the solution set, we set each factor equal to zero: x7=0orx+2=0x - 7 = 0 \quad \text{or} \quad x + 2 = 0

Solving these equations gives: x=7orx=2x = 7 \quad \text{or} \quad x = -2

Therefore, the solution set is: {7,2}\{7, -2\}
