No. Your answer is right.(x + 8) (7x + 2) = 7x² + 56x + 2x + 16 = 7x² + 58x + 16

ok so the variable is c u might desire to have (c+something)(c+something) and the numbers u use could upload as much as the b and multiply c of ur equation a = a million b= 4 c = 4 so what 2 numbers upload as much as 4 and multiply to 4...2 so while u element it ur solutions is (c+2)(c+2) desire i helped

7x^2 + 58x + 16
= 7x^2 + 56x + 2x + 16
= (7x^2 + 56x) + (2x + 16)
= 7x(x + 8) + 2(x + 8)
= (x + 8)(7x + 2)
= 7x^2 + 56x + 2x + 16
= (7x^2 + 56x) + (2x + 16)
= 7x(x + 8) + 2(x + 8)
= (x + 8)(7x + 2)

7x^2+58x+16
7x^2+56x+2x+16
7x(x+8)+2(x+8)
(x+8)(7x+2)
Note:
16 x 7 = 112
56 x 2 = 112
split 58 as 56 & 2
7x^2+56x+2x+16
7x(x+8)+2(x+8)
(x+8)(7x+2)
Note:
16 x 7 = 112
56 x 2 = 112
split 58 as 56 & 2

(7x+2)(x+8) is correct
(7x)(x) + (7x)(8) + (2)(x) + (2)(8)
7x² + 56x + 2x + 16
7x²+58x+16
(7x)(x) + (7x)(8) + (2)(x) + (2)(8)
7x² + 56x + 2x + 16
7x²+58x+16

You got it right. Expanding it out: x^2 + 56x + 2x +16
2008-08-11 4:02 pm
7x^2 + 58x + 16
(7x + 2 ) (x + 8)
You have the correct factoring when you apply the FOIL method you see that the 7x * 8 is added to the additional 2 * x. Which gives you that additional 2x you were missing.
(7x + 2 ) (x + 8)
(7x * x) + ( 7x * 8) + (x * 2) + (2 * 8)
7x^2 + 56x + 2x + 16
7x^2 + 58x + 16
(7x + 2 ) (x + 8)

(x + 8)(7x + 2) = 7x^2 + 2x + 56x + 16, or
7x^2 + 58x + 16.
Looks like you just did your arithmetic wrong; the factoring was right.
Hope this helps.
