A.(3x^2-5x+4)2x^2
b.(2x-y)(3x^2+y^2+4xy)

Sarika why (3 x square - 5 x + 4) close to x through the answer is that it was present that answer is total answer is total answer is total answer is giving after the answer is 30 saved why because you will do divide first then you are saying ok second 2 x minus y bracket close 3 X 2 + 22 x 4 x 5 FIR Aisa Sohail Kuchh Bhi Nahin Hai Mere Ko To Sare Walaikum and don't forget to

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
