Answer:
1/204.
Step-by-step explanation:
That would be
6/18 * 5/17 * 4/16 * 3/15
= 1/3 * 1/4 * 1/5 * 5/17
= 5/1020
= 1/204.
Multiply it then you’ll get your answer

Answer:
Step-by-step explanation:
<u>Given expression</u>:
To factor a quadratic in the form 
, first find two numbers that multiply to 
and sum to 
:
Two numbers that multiply to -36 and sum to 5 are: 9 and -4
Rewrite b as the sum of these two numbers:
Factorize the first two terms and the last two terms separately:
Factor out the common term (2x + 3):
Therefore:
<em> x₁ = - 1</em>
<em> x₂ = 2</em>
- Step-by-step explanation:
<em>2²ˣ⁺¹ - 9ₓ2ˣ + 4 = 0</em>
<em>2²ˣₓ2 - 9ₓ2ˣ + 4 = 0</em>
<em>2ˣ = n</em>
<em>2n² - 9n + 4 = 0</em>
<em>2n² - n - 8n + 4 = 0</em>
<em>n(2n - 1) - 4(2n - 1) = 0</em>
<em>(2n - 1)(n -4) = 0</em>
<em>2n - 1 = 0 => n₁ = 1/2</em>
<em>n - 4 = 0 => n₂ = 4</em>
<em />
<em>2ˣ = 1/2 => 2ˣ = 2⁻¹ => x₁ = - 1</em>
<em>2ˣ = 4 => 2ˣ = 2² => x₂ = 2</em>
