Answer:
= (x-4)(x-3)
Step-by-step explanation:
Firstly, put the pronumeral in the brackets [(x)(x)].
Then, place the signs in the right positions, the sign of the constant number (12) is a positive (+), therefore the two signs must be the same. The sign of the -7x is negative (-). Place these in the brackets [(x-)(x-)].
Next, think of the factors of 12 that add up to 7 {(3 and 4) 3x4 is 12 and 3+4 is 7}. [(x-4)(x-3)].
Have a nice day!!!!!!! :-)

Answer:
(x-3) (x-4)
Step-by-step explanation:
x²- 7x + 12
= x² - 3x -4x +12
=x(x-3) - 4(x-3)
=(x-3) (x-4)
In standard form, it would be 0.000000146

Rule of rounding number :
1) When the rounded place value after digit is less than 5 then the number remain same.
2) If the rounded place value after digit is 5 or greater than 5 then the number round by 1.
710,430 is rounded to 700,000.
