What are the zeros in the function f(x)=(2x+6)(x-4)

Hello from MrBillDoesMath!

Answer:

x = -3, 4

Discussion:

The zeroes of f(x) are the x values where

2x + 6 = 0 => x = -3

and

x - 4 = 0 => x = 4

Thank you,

The sum of the reciprocals of two consecutive even integers is 3/4 Find the two integers.

Vedmedyk [2.9K]

$\Large{ \underline{ \underline{ \bf{ \orange{Solution:}}}}}$

Let one of those even numbers be x, Then other even number would be x + 2.

According to question,

⇛ Their reciprocal add upto 3/4

So, we can write it as,

⇛ 1/x + 1/x + 2 = 3/4

⇛ x + 2 + x / x(x + 2) = 3/4

⇛ 2x + 2 / x² + 2x = 3/4

Cross multiplying,

⇛ 3(x² + 2x) = 4(2x + 2)

⇛ 3x² + 6x = 8x + 8

⇛ 3x² - 2x - 8 = 0

⇛ 3x² - 6x + 4x - 8 = 0

⇛ 3x(x - 2) + 4(x - 2) = 0

⇛ (3x + 4)(x - 2) = 0

Then, x = -4/3 or 2

☃️ It can't be -4/3 because it is fraction and negative number. So, x = 2

Then, x + 2 = 4

✤ So, The even numbers are 2 and 4.
