Answer: The correct factors are
(x-1) and (x+2)
Step-by-step explanation:
Step one :
To factorize the equation
x²– x – 2=0
First we look for numbers that when multiplied will result to the constant term and when added will result to the second term (1x, - 2x)
Step two :
We replace the second term with these factors we have
x²–(x-2x)–2=0
x²–x+2x–2=0
Factoring the expression we have
x(x–1)+2(x–1)=0
Hence the factors will be
(x-1) and (x+2)
Answer:
475
Step-by-step explanation:
Is means equals. We need to change 8% to a decimal. 8% = .08. Of means multiply. X is the unknown number.
38 = .08 * x
Divide each side by .08
38/.08 = .08x /.08
475 = x
The unknown number is 475
