this was high school math for me... I don't remember how to do it, but this was high school math.

I wish you would give a progression out line of where to start learning about polynomials starting with the basics

@user-ri6rn7ti5h 9 месяцев назад

(a+1a-3) (a+2a-2)

@danieldennis9831 11 месяцев назад

a=+i,-i,2,-2 ... which might be wrong .. I factored out (a²+1)(a²-4)=0, a²=-1 a²=4 which is ±i and ±2 ... I thnk

At the end of your stuff you've got plus minus ''i'' but you forgot square root of minus plus 2. Not just plus minus 2.

Right answer.

Is it weird that I started on solving multi variable derivatives and integrals before really learning college algebra? I did pretty well with algebra in school so I decided to jump right into the deep end and I've been back peddling to fill in some gaps, but doing this has definitely increased my learning rate because I feel like I have this incentive to pick up these principals and run with them. If I had started with the mundane stuff like continuity, analyzing functions and graphs.. then I would not have stuck with learning maths and engineering.

How can I differentiate a polynomial from a quadratic equation

a=2

explain

@fred8780 6 месяцев назад

yes, the explanation was awful. step 1: cubical. ax^3 + bx^2 + cx + d; becomes 1x^3 + 1x^2 + 0x - 36; a^3 + a^2 - 36; notice the last term is negative. factors of 36: 1,36,2,18.3,12,4,9. try each f(x) factor to see what = 0; 3 works a-3=0; have students do division. (a^3 + a^2 - 36)/(a-3) (a-3)(a^2 +4a +12) use the quadratic formula. 1 real and 2 imaginary.
