2x2 - 11x + 15 when factorised gives _________.
(2x + 5)(x + 6)
(x + 5)(x + 6)
(x - 5)(x - 6)
(x - 3)(2x - 5)
Splitting the middle term of the given expression such that the sum is -11 and product is 30, we get
Hence, (x - 3) and (2x - 5) are the factors of 2x2 - 11x + 15.
Factorise: x2+10x+25
2x2+5x+3=?(a) (x+3)(2x+1)(b) (x+1)(2x+3)(c) (2x+5)(x−3)(d) none of these
If 5x+72=32x−14, then x = ?
(a) 5
(b) -5
(c) 6
(d) -6
