## anonymous one year ago Can anyone give me a "hard" factoring polynomial equation? (If possible, the question can have the combination of factoring techniques.)

Okay, I'll give you a warming up one, factor this: $6a^2+14b-8-11ab+4b^2-8a$

factor $$x^3 + 7x^2 + 14x +8$$

3. anonymous

factor $$x^2-8x+17$$ without using the quadratic formula or completing the square to find the roots first

4. anonymous

cough cough $$x^2-2ax+a^2+b^2=(x-(a+bi))(x-(a-bi))$$ so $$x^2-8x+17=x^2-8x+16+1=(x-(4+i))(x-(4-i))$$

also $$x^3+7x^2+14x+8=x^3+6x^2+8x+x^2+6x+8=(x+1)(x^2+6x+8)\\\quad\quad\quad=(x+1)(x+2)(x+4)$$
