What are the zeros of the function?

p(x) = x² – 10x + 21

Sagot :

Answer: 3 and 7 by x^2 -10x + 21 factoring to (x-7)(x-3)

Or by putting a,b and c values (which are 1, -10 and 21) in the quadratic formula

Step-by-step answer:

Zeros of a function are the values that you plug in for x (the input of the function) so that the output (the y) is equal to 0.

So what x values do you make x^2 -  10x + 21 = 0, that's the same question as how do you solve for x you have to methods that are kinda equivalents

1-Factorization

2-Quadratic formula

1-Factorization. Because a = 1 (ax^2 = 1×x^2)
