Answer:
(2x + 3 + 2√6)(2x + 3 - 2√6)
Step-by-step explanation:
<u>Factorization in steps</u>
- 4x^2 + 12x- 15=
- (2x)^2 + 2*2x*3 + 3^2 - 9 - 15 =
- (2x + 3)^2 - 24 =
- (2x + 3 + √24)(2x+3 - √24) =
- (2x + 3 + 2√6)(2x + 3 - 2√6)
Answer:
48nc
Step-by-step explanation:
The LCD of one expression is the expression itself.
Answer:
first number=15 second number=6
Step-by-step explanation:
lets take the first and second numbers as "a" and "b"
a-b=9
a+2b=27 (solve these equations simultaneously)
eliminating a
-3b= -18
b= 6
then substitute in the first equation
a-6=9
a=9+6
a=15
I really hope you know how to solve equations simultaneously
hope this helped
