3x^2-3x-2x+2
now, we take common
3x(x-1)-2(x-1)
(x-1)common and (3x-2)
(x-1)(3x-2)
The volume of cuboid is given by the expression x3+2x2-x-2. The dimension of the cuboid for x = 5 is:
Factorise the quadratic polynomial by splitting the middle term:
x2 + 14x + 45
The two numbers that add up to 14, and multiply to 45 and 9 and 5.
(x+5)(x+9)
Factorize the quadratic polynomial by splitting the middle term: y2 – 4 y –21
P(x) = ×2-6×+p
p (2)= (2)2-6 (2) +p
4- 12 + p
-8 + p
p = -8
