True and false if false then give reason (i) y 3 + 5 y 2 + y + 6 is a polynomial. (ii) (x − 3) is a factor of x 2 + 2x − 15. (iii) (a − b) (a + b) is a binomial. (iv) (x − 5)2 = x 2 − 10x − 25. (v) To find the value of 252, we use the identity, a 2 − b 2 (a + b) (a − b). Share with your friends Share 0 Atul Shaw answered this 1 View Full Answer
