Which of the following are the factors of a2 + ab +bc + ca
The number of zeros of x2 + 4x + 2
Factorise by splitting the middle term 2x2 - 11x + 12
The volume of cuboid is given by the expression x3+2x2-x-2. The dimension of the cuboid for x = 5 is:
Expansion of 2x(x + 2y) + 3x(2x - 3y) yields
What are the two factors of quadratic polynomial x2-16x+64?
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.
Factorize the quadratic polynomial by splitting the middle term: y2 – 4 y –21
What is the value of p if x-2 is a factor of x2 – 6x + p ?
P(x) = ×2-6×+p
p (2)= (2)2-6 (2) +p
4- 12 + p
-8 + p
p = -8
