Answer:
[tex](x-3)(x-10)[/tex]
Step-by-step explanation:
To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to 30 and add to -13 for a and b.
30: 1, 2, 3, 5, 6, 10, 15, 30
-3+-10 = -13
[tex]x^2-13x+30 = (x-3)(x-10)[/tex]
