Factoring the Quadratic Equation
Now, let’s immerse ourselves in the intricate process of factoring the equation x2-11x+28=0.
Identify the Coefficients
- A = 1
- B = -11
- C = 28
To commence the factoring process, it is imperative to identify the coefficients of the equation, which in our case are: A = 1, B = -11, and C = 28.
Find Two Numbers
Factoring a quadratic equation necessitates the discovery of two numbers that, when multiplied, yield the product ‘A * C’ (in this instance, 1 * 28) and simultaneously add up to ‘B’ (which, in our case, is -11). The numbers we seek are -7 and -4, for the product of (-7) * (-4) indeed equals 28, and their sum, (-7) + (-4), equivalently amounts to -11.
