Factor each expression completely. If an expression is prime, so indicate. $$x^{2}-2 x+15$$
Added by Stephanie H.
Step 1
These numbers are -3 and -5. So we can rewrite the expression as: $$x^2 - 3x - 5x + 15$$ Now we can factor by grouping: $$(x^2 - 3x) - (5x - 15)$$ $$x(x - 3) - 5(x - 3)$$ $$(x - 5)(x - 3)$$ Show more…
