See, We can split 30 as 5√3 × 2√3 Which is 5×2=10 and √3×√3 =√9 And we know that √9=3 Next you have to do the middle term factorisation. Split 3√3 as 5√3 - 2√3, so you got the answer

Anurag Sonkar 2 years, 6 months ago

P(x)=5x^3-2x^2 +3x-2 When the value of x=1 Then the answer is Put the value 2 on the place of x Then , we get 5×1^3-2×1^2+3×1-2 We know that , When 1 is multiply by any time of mo 1 we get 1 So,5×1-2×1+3×1-2 =5-2+3-2 We apply the BODMAS formula in that value =5+1-2 =6-2 =4 Answer is 4
