Factoring in AlgebraFactors
Numbers have factors:
And expressions (like <span>x2+4x+3</span>) also have factors:
Factoring
Factoring (called "Factorising" in the UK) is the process of finding the factors:
Factoring: Finding what to multiply together to get an expression.
It is like "splitting" an expression into a multiplication of simpler expressions.
<span>Example: factor 2y+6</span>
Both 2y and 6 have a common factor of 2:
<span>2y is 2 × y6 is 2 × 3</span>
So you can factor the whole expression into:
2y+6 = 2(y+3)
So 2y+6 has been "factored into" 2 and <span>y+3</span>
Answer:
190.08
Step-by-step explanation:
It is a <span>Fibonacci Sequence:
So the missing number is 5 + 8 = 13</span>
Answer: y = 2.1
Step-by-step explanation:
Considering the given triangle XYZ, to determine side y, we would apply the sine rule. It is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes
x/SinX = y/SinY = z/SinZ
Therefore
y/Sin 15 = 8/Sin 94
Cross multiplying, it becomes
ySin94 = 8Sin15
0.998y = 8 × 0.259
0.998y = 2.072
y = 2.072/0.998
y = 2.1
