Answer:
Here, , hence the quadratic equation has two distinct real roots.
Step-by-step explanation:
Given quadratic equation is .
Let, the quadratic equation is [where, are the constants]
The Discriminant
Case : , if the discriminant is greater than , it means the quadratic equation has two real distinct roots.
Case : , if the discriminant is less than , it means the quadratic equation has no real roots.
Case : , if the discriminants is equal to , it means the quadratic equation has two real identical roots.
Now,
we have , where
∴
Here, , hence the quadratic equation has two distinct real roots.

Answer:
(a) 2 (17 + 8)
Step-by-step explanation:
The largest common factor is 2.
34 +16 = 2·17 +2·8 = 2(17 +8)
Expanded for shows how do u get the number and when u multiply it's like EX: 3 times .01 which is .03 so that's how is show u in expanded form and word from is showing how u say is and the place it's at EX: twenty-one and four tenths shows it's 21.4.
Answer:
Step-by-step explanation:
Required
Simplify
Solving (1):
Factorize the numerator and the denominator
Factor out x+2 at the numerator
Express x^2 - 9 as difference of two squares
Expand the denominator
Factorize
Cancel out same factors
Hence:
Solving (2):
Expand the numerator and factorize the denominator
Factorize the numerator
Factor out x - 2
Cancel out x - 2
Hence:
Solving (3):
Express x^2 - 9 as difference of two squares
Factorize all:
Cancel out x + 3 and 3 + x
Express as
Hence:
Solving (4):
Expand x^2 - 6x + 9 and factorize 5x - 15
Factorize
Cancel out x - 3
Change / to *
Express as
Hence:
Solving (5):
Factorize the numerator and expand the denominator
Factor out x - 1 at the numerator and factorize the denominator
Express x^2 - 1 as difference of two squares and factor out x - 1 at the denominator
Hence:
Solving (6):
Factorize:
Divide by 3x
Hence:
Solving (7):
Change / to *
Expand
Factorize
Cancel out x - 2 and x - 1
Cancel out x
Hence:
