Answer with explanation
When you look at whole numbers , it begin from Zero and has no end , and decimal ,which is the set of rational numbers and irrational numbers, which came into consideration after whole numbers.
Whole number =0,1,2,3,4,5,6......
Decimal number = 0.1,0.25,0.325, 0.002000200002000002,..........
→0 × Any Decimal number =0
→ Any other whole number × A decimal number, gives
Convert that decimal into equivalent fraction,or if irrational number,write it up to three decimal places, and then multiply numerator with Numerator as denominator will remain unchanged to get the required result or multiply the decimal number with the whole number.
For example
→ Whole number × Terminating Decimal
5 × 0.25
→Whole number × A non terminating repeating Decimal
2×0.22222222.......
= An rational number, that is non terminating repeating decimal.
→→Whole number × An irrational number (A non terminating non repeating Decimal)
5 × √2=5 ×1.414(written to three decimal places)
=7.07(approx)
So, when there is an irrational number , write that decimal up to three decimal places, and then multiply that whole number by that irrational or decimal number to get the result.
Answer:
1. (x+5)(x-1)
6. (3x+4)(x-6)
9. (x+5)(x-5)
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:
Regular: Find two numbers that multiply to C and add to B from .
Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.
Difference of Squares: Factor by taking the square root of each term.
