You can first take out an x^2 from each number , 3x^6 - 39x^4 + 108x^2 = x^2 ( 3x^4 - 39x^2 + 108) Then just factor and solve for the zero's of the equation
Answer:
Distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac. From this law it is easy to show that the result of first adding several numbers and then multiplying the sum by some number is the same as first multiplying each separately by the number and then adding the products.
Step-by-step explanation:
a(a+b)
in this question first a will multiply by a+b.
like this;
a(a+b)
= a(a)+ab
= a^2+ab
Answer:
6/1
Step-by-step explanation:
He read 90 pages in 3 hours so it's 30/1 pages/hour
Then he reads 180 pages in 5 hours so it's 36/1 pages /hours
the rate of difference is 30/1 ÷ 36/1 is 6 pages per hour
