Factored form of an expression is writing it in the terms of multiplication of factors. The factors of given expression are: (7x+4)  and (x-1)

<h3>How to find the factors of a quadratic expression?</h3>

If the given quadratic expression is of the form ax^2 + bx + c,

then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:

b = \alpha + \beta \\ ac =\alpha - \beta

The given expression is 7x^2 - 3x - 4

Comparing it with the standard form of quadratic expression ax^2 + bx + c, we get: a = 7, b = -3, c = -4

ac = -28

-28 = -2 times 14

-28 = -7 times 4 (-7 + 4 = -3 = b)

Thus, \alpha = -7, \beta = 4

Thus, we get:

7x^2 - 3x - 4 = 7x^2 - 7x + 4x - 4 = 7x(x-1) + 4(x-1)  = (7x+4)(x-1)\\7x^2  - 3x  - 4 = (7x+4)(x-1)

Thus, The factors of given expression are: (7x+4)  and (x-1)

What is 710,200 written in word form
Julli [10]
<span> For this case we have the following number: 
 710200
 We are going to decompose this number as the sum of three numbers:
</span> 710200 = 700000 + 10000 + 200&#10;
<span> Let's now write each number:
 70000: seven hundred thousand
 10000: ten thousand
 200: two hundred
 Therefore, the complete expression is:
 Seven hundred ten thousand two hundred
 Answer:
 Seven hundred ten thousand two hundred</span>
