The volume of cuboid is given by the expression x^{3}+2x^{2}x2. The dimension of the cuboid for x = 5 is:
What are the two factors of quadratic polynomial x^{2}16x+64?
Factorise the quadratic polynomial by splitting the middle term:
x^{2} + 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: y^{2} – 4 y –21
What is the value of p if x2 is a factor of x^{2} – 6x + p ?
P(x) = ×^{2}6×+p
p (2)= (2)^{2}6 (2) +p
4 12 + p
8 + p
p = 8
