Answer:
correct choice is marked
Step-by-step explanation:
The error is in step 2. The square root cannot be distributed to a sum.
1. -1•5•5 or also -1•5²
2. -1•7•7 -1•7²
3. -1•7
4. -1•13
5. -1•2•2•2•3 -1•2³•3
6.-1•2•2•2•2•3 -1•2^4•3
7. -1•2•2•2•3•7 -1•2³•3•7
Both factorization are correct it just depends on your teacher how she/he wants you to write it.
See the solution in the pdf file attached. Please, let me know if it is satisfactory for you.
That's Intersecting Secants, and we get
EC × ED = EB × EA
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 9x + 20 = x^2 + 13x + 12
8 = 4 x
x = 2
Check: 3(14)=42 6(7)=42 good
Answer: 2
Answer:
The value of Discriminant of the function is -92
It has ZERO distinct real number zeros.
Step-by-step explanation:
Given:
Which is a Quadratic Equation in the general form of
where a,b and c are constants.So on comparing the given equation with general form we get,
Formula for discriminant we have
now for zeros we have
on substituting these values we get
or
the term 
is imaginary
hence the zeros are not real number
