Select the two values of x that are roots of this equation. 3x-5=2x^2​

Mathematics

Korolek [52]3 years ago

Solution:

3x - 5 = -2x²

2x² + 3x - 5 = 0

<em>By splitting the middle term,</em>

2x² - 2x + 5x - 5 = 0

2x (x - 1) + 5 (x - 1) = 0

(2x + 5)(x - 1) = 0

So, 2x + 5 = 0

<em>x = -5/2</em>

(OR)

x - 1 = 0

<em>x = 1</em>

The roots of <em>2x² + 3x - 5 = 0</em> are: A. x = 1 & B. x = -5/2

Step-by-step explanation:

3x - 5 =  -  {2x}^{2}

➡

{2x}^{2}  + 3x - 5 = 0

(2x+5)(x-1) = 0

one of these multiple should be 0 so the equation is equal to 0

therefore if 2x + 5 = 0 then

x = -5/2

and if x+1 = 0 then

x = 1

Answer:

Kindly check explanation

Step-by-step explanation:

Learning could be explained as a process of acquiring knowledge about a certain subject, trade or other aspects of life. In terms of learning about certain school subjects, a student needs to discover him or herself in other to make acquiring knowledge easy and less tedious for him or her.

The area of a circular wave expands across a still pond such that its radius increases by 14 cm each second. Write a formula for
lara31 [8.8K]

Answer:

A = π(14t)²

Step-by-step explanation:

The radius is increasing at the rate of 14 cm per second.

We need to find the formula for the area A of the circle as the function of time t.

Initial area of the circle,

A = πr², where r is the radius of the circle

Area as a function of t will be :

A = π(14t)²

Here, 14t is the radius of the wave.
