Expand x(x – 4)<br> Please answer!!! I will mark you as brainliest if you answer and its right!!
Mekhanik [1.2K]

The expression x( x - 4 ) when expanded is x² - 4x

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.

When a bracket is expanded, each term is multiplied by the expression outside of the bracket.

The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.

Consider the expression,

x( x - 4 )

Let us assume y = x( x - 4 )

Using the distributive property, a( b + c ) = ab + ac

y = x( x - 4 )

y = x · x - x · 4

y = x² - 4x

Therefore, x( x - 4 ) = x² - 4x

Therefore, the expression when expanded is x² - 4x.

The diagram below shows the graph of the quadratic function f (x) = ax² + 8x + c. calculate the value for each of the following.
Alexxandr [17]

Answer:

see explanation

Step-by-step explanation:

The y- intercept is at (0, 6) ⇒ c = 6

The x- coordinate of the vertex is at the midpoint of the zeros, that is

m = \frac{-3-1}{2} = \frac{-4}{2} = - 2

Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and

f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)

Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2

Thus

f(x) = 2x² + 8x + 6

Substitute m = - 2 into the equation for value of n

n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2

Hence

c = 6, m = - 2, a = 2, n = - 2
