Answer:(x - 1)(7x + 12)
Step-by-step explanation:
Question: (6x² + 5x - 3) + (x² - 9)
⇒(6x² + 5x - 3) + (x² - 9)
⇒6x² + 5x - 3 + x² - 9
rearrange
⇒6x² + x² + 5x - 3 - 9
⇒7x² + 5x - 12
Middle term break
⇒7x² + 12x - 7x - 12
⇒x(7x + 12) - 1(7x + 12)
⇒(x - 1)(7x + 12) Answer
hope that helps...
Answer:
Step-by-step explanation:
I assume by x2, you mean x^2.
Anyways, subtracting both sides by 12x, we get 17x^2 -12x=0.
What you have written here is an equation.
You can define as
a2+b2=y
If you want to derive a^2+b^2 from ( a+b)^2
(a+b)2=a2+b2+2ab
Ora2+b2=(a+b)2−2ab
Pretty sure it’s obtuse !
12.5%
<span>to convert from percent to decimal: divide by 100, and remove the "%" sign.

12.5 ÷ 100 = 0.125
