Answers
Answer:
step 1
Address the formula and input values.
Input values:
The given fraction = 220/140
step 2
Find GCD (Greatest Common Factor) for both numerator and denominator.
The GCF for 220 and 140 is 20
step 3
divide the numerator and denominator by GCD 20 and rewrite the fraction
= (220/20) / (140/20)
= 11/7
11/7 is the simplified fraction for 220/140 by using the GCD or HCF method.
Prime Factorization Method :
step 1
Address input values.
Input values:
The given fraction = 220/140
step 2
Find prime factors for both numerator and denominator and rewrite the fraction in the form of prime factors
Prime factors for 220 = 2 x 2 x 5 x 11
Prime factors for 140 = 2 x 2 x 5 x 7
= (2 x 2 x 5 x 11) / (2 x 2 x 5 x 7)
step 3
solve and rewrite the fraction
= ( 11)/( 7)
= 11/7
11/7 is a simplified fraction for 220/140 by using the prime factorization method
Answer:
We will discuss here about the expansion of (x ± a)(x ± b). (x + a)(x + b) = x(x ... (x + a)(x + b) = x2 + (Sum of constant terms)x + Product of constant terms. ... Product = (x – 3)(x + 2). = x2 + (-3 + 2)x + (-3) ∙ 2. = x2 – x – 6. Now plug-in x = 2m + n.
