If x=-5 is a zero, then the first factor of the polynomial would be (x + 5 )
To find the other two factors we can divide the polynomial by the expression (x+5).
Using synthetic division, we have:
-5 I 4 15 -24 5 (Coefficients of the dividend)
I -20 25 -5 (Multiplying each coefficient by the results of the substraction and adding)
-----------------------------------------------------------------------------------
4 -5 1 0 (Coefficients of the quotient)
The result of the division is 4x^2 - 5x + 1. Factoring it, we have:
4x^2 - 4x -x + 1 (Separating -5x into -x and -4x)
4x (x - 1) - (x -1) (Factoring each pair of terms)
(x-1)(4x-1) (Factoring using the common factor)
So the answer would be:
(x + 5 )(x-1)(4x-1)
Answer:
Step-by-step explanation:
2 if you mean 1 of each so it would be 50 cards
Answer/Step-by-step explanation:
Scale factor: 1/4
<em>AC = DF and 10 ÷ 2.5 = 4</em>
<em>10 x 1/4 = 2.5</em>
<em />
DE length: 5
<em>AB = DE </em>
<em>20 x 1/4 = 5</em>
<em />
BC length: 30
<em>EF = BC</em>
<em>(Because EF is the dilation) 7.5 x 4 = 30</em>
