53y - 55 = 42y

53y - 42y = 55

11y = 55

11y/11 = 55/11

y = 5 (Hope this helped!)

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

Sladkaya [172]

<h3>Answer:</h3>

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

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

<h3>Hence option A is correct .</h3>
