Question

obtain all other zeroes of the polynomial x^4 + x^3 - 4x + 48 , if two of its zeroes are 2 and -4. PLEASE TAKE A PHOTO OF THE SOLUTION OR EXPLAIN FULLY

Answer 1

quad equation

x4+x3-4x+48-------1

two zeroes 2 and -4

[x+2] or [x-4]

x2-4x+2x-8

x2-2x-8----------2

now divide =1 by =2

x2-2x-8/x4+x3-4x+48

after dividing just split the midle term of the quotient

there u will get other two zeroes

hope u will understand

yess to alll
