Mathematics
1 answer:
creativ13 [48]3 years ago
5 0

Answer:

see explanation

Step-by-step explanation:

(4 - 7y)(7 + 4y)

Each term in the second factor is multiplied by each term in the first factor, that is

4(7 + 4y) - 7y(7 + 4y) ← distribute parenthesis

= 28 + 16y - 49y - 28y² ← collect like terms

= 28 - 33y - 28y² or

- 28y² - 33y + 28 ← in standard form

Write 3x^2-18x-6 in vertex form
Vedmedyk [2.9K]
The standard form of a quadratic equation is \displaystyle{ y=ax^2+bx+c, while the vertex form is:

                      y=a(x-h)^2+k, where (h, k) is the vertex of the parabola.

What we want is to write \displaystyle{ y=3x^2-18x-6 as y=a(x-h)^2+k

First, we note that all the three terms have a factor of 3, so we factorize it and write:

\displaystyle{ y=3(x^2-6x-2).


Second, we notice that x^2-6x are the terms produced by (x-3)^2=x^2-6x+9, without the 9. So we can write:

x^2-6x=(x-3)^2-9, and substituting in \displaystyle{ y=3(x^2-6x-2) we have:

\displaystyle{ y=3(x^2-6x-2)=3[(x-3)^2-9-2]=3[(x-3)^2-11].

Finally, distributing 3 over the two terms in the brackets we have:

y=3[x-3]^2-33.


Answer: y=3(x-3)^2-33
