2(x-2)=6 Multiply OUT brackets; 2 times X, 2 times -2 2x-4=6 The -4 goes to the other side, therefore becoming +4 2x=6+4 2x=10 The 2 is in its times form, by bringing it to the other side, it becomes a divide. x=10 divided by 2 x=5 to check, substitute 5 into the equation: 2(5-2)=6 2(3)=6 2*3=6

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.
