f(x) = (x + 5)(x - 1)
using the ' factor theorem '
given x = a is the root of a polynomial then (x - a ) is a factor
here roots are x = - 5 and x = 1 hence factors are (x + 5) and (x - 1)
the polynomial is the product of the factors
f(x) = (x + 5)(x - 1)
Here is your answer:
7. 3×1=3
7×1=7
2. 5×1=5
7×1=7
=5 -2/7
Step one: write the equation
Step two: find the common denommarator (which is 7)
Step three: subtract 3-5= which equals to negative 2
Step four: subtract the whole numbers ( 7 and 2) which gives you five
Your answer is...
5 -2/7
First, find the value of the expression within the parentheses, which is 8x. Since x=1/4, 8x=8/4 or 2. Next, multiply this value by -3. -3*2=-6
Answer: A and B
<u>Step-by-step explanation:</u>
Here is Pascal's Triangle:
Row 1 (x + y)⁰ 1
Row 2 (x + y)¹ 1 1
Row 3 (x + y)² 1 2 1
Row 4 (x + y)³ 1 3 3 1
Row 5 (x + y)⁴ 1 4 6 4 1
∵
Row n (x + y)ⁿ⁻¹ 1 (sum of 2 digits above) 1
C and D are false. A and B are the only correct answers
