1. Square of a Binomial Symbols/Pattern:
(+b) = 2 + 2 b + B²
( - b) ² = =-2 b +62
In the pattern, if is the first term and b is the last term, then the square
of a binomial consists of:
a) the square of the first term):
b) twice the product of the first and last terms (2b): and
c) the square of the last term (b).
2. The product of the sum and difference of two terms

(x+3)(x+7)

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
