Write the function a a product of linear factor by grouping or using the x method or a combination of both

Sladkaya [172]

<h3><u>Answer:</u></h3>

$\boxed{\boxed{\pink{\sf Option \ A \ is \ correct .}}}$

<h3><u>Step-by-step explanation:</u></h3>

Given function to us is :-

$\bf \implies g(x) = x^2 - 9$

And we , need to write the function a a product of linear factor by grouping or using the x method or a combination of both . So let's factorise this ,

$\bf \implies g(x) = x^2 - 9 \\\\\bf\implies g(x) = x^2-3^2\\\\\bf\implies \boxed{\red{\bf g(x) = (x+3)(x-3) }}\:\:\bigg\lgroup \blue{\tt Using \ (a+b)(a-b) \ = a^2-b^2 }\bigg\rgroup$

I have also attached the graph of x²-9.

Find the solutions <br> x^2=16x-28

ioda

Minus 16x both sides and add 28 to both sides
x^2-16x+28=0
factor
hmm, what 2 numbers multiply to 28 and add to -16
hmm
1 and 28? nope
2 and 14? yep
since middle term is negative and last tem is positive, both of the factors are negative

(x-14)(x-2)=0
set each to zero
x-14=0
x=14

x-2=0
x=2

x=2 and 14

Math 7a using number sense to solve equations

Anika [276]

Simple...

you have: $\frac{n}{3} =12
$

and

$\frac{n}{3} =-12$

To solve for.... $\frac{n}{3} =12$

Multiply to remove the denominator-->>

$3* \frac{n}{3} =12*3$

n=12*3

n=36

Then-->>>

$\frac{n}{3} =-12$

Do the same thing-->>

$3* \frac{n}{3} =-12*3$

n=-12*3

n=-36

Thus, your answer.
