there are 5 question please solve all


who solve all I make him branlist..​

Answer 1

Step-by-step explanation:

10. if this happens then on p(a) will be zero

11. 5/7= 0.714..≈

9/11= 0.8181..≈

so three different irrational numbers btvn these are

0.727302747637389...

0.759236384972847...

0.802837382733...

12. if x+1 is factor then on substituting x=-1in polynomial we get zero as reminder

so let's substitute

2(-1)^2+k(-1)+1=0

k=3

14. for first factor we will use hit and trial method

bythis I got -1 as its root

so on dividing it by x+1 we get

(x+1)(x^2+12x+20)

now on further factorisation

(x+1)(x+10)(x+2)

please replace m with x
