49x
You need at least two terms to find a GCF.
49
49x.
98x
4x2+49x+90 = (4x+9)(x+10) when factored
One can purchase a used HP 49X from the Amazon Marketplace on the Amazon website. One may also find a used HP 49X for sale via the eBay website although this is dependant on individual users wanting to sell their items.
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
To factor the expression ( 7X^3 + 49X^2 + 84X ), first, identify the greatest common factor (GCF) of the terms, which is ( 7X ). Factoring out ( 7X ) gives ( 7X(X^2 + 7X + 12) ). Next, you can further factor the quadratic ( X^2 + 7X + 12 ) into ( (X + 3)(X + 4) ). Thus, the fully factored form is ( 7X(X + 3)(X + 4) ).
(7x + 4)(49x^2 - 28x + 16)
(7x + 6)(49x^2 - 42x + 36)
7x2+49x-42 = 7(x2+7x-6)
