Answer:
6(x - 1)(3x + 1)
Step-by-step explanation:
Given
18x² - 12x - 6 ← factor out 6 from each term
= 6(3x² - 2x - 1) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 1 = - 3 and sum = - 2
The factors are - 3 and + 1
Use these factors to split the x- term
3x² - 3x + x - 1 ( factor the first/second and third/fourth terms )
= 3x(x - 1) + 1(x - 1) ← factor out (x - 1)
= (x - 1)(3x + 1)
Hence
18x² - 12x - 6 = 6(x - 1)(3x + 1) ← in factored form
9x^2 + 24 x + 16 = 0
(3x +4) (3x + 4) = 0
x=-4/3
are you sure part A doesn't have a negative somewhere?
9x^2+12x+12x+16 this works just double checking
b)
16x^2 - 25y^2 = 0
(4x-5y)(4x+5y)= 0
hope this helps
30/75 = 12/x
30*x=75*12
30x=900/:30
x=30
This is basically the answer. I found it online so here ya go.
Answer: The answer is 315.
