Question

x4 - 2x3 - 7x2 + 8x + 12
​

Answer 1

My handwriting might disturb you But , the answer might help you Since 2 and -2 are the zeroes,(x-2) and (x+2) are factors. that is x^2-4 is a factor. divide the polynomial by g(x)=x^2-4,you get q(x)=x^2+2x-3 r(x)=0 factorise q(x) by splitting the midd le term method you get the other zeroes x=1 and x=-3 ALL THE BEST FOR YOUR EXAM!!!!!!!!

Answer 2

Answer:

13/2

Step-by-step explanation:

x4 - 6 - 14 + 8x + 12 = 0

= x4 - 8 + 8x + 12 = 0

= x4 + 8x = 2

= x4 + x = 20/

= x4 + x = 5/

= x^2 = 5/2 + 4

= x^2 = 13/2
