Times 16 times 25 = 400
now what times to 400 and adds to 40
list the things that add to 40=
5+35 = 40 but 5 times 35 is 175 so it doesn't work
10+30 = 40 but 10 times 30 is 300 so it doesn't work but going in the right direction
20 +20 = 40 and 20 times 20 is 400 so we found our factors
(16X+20) (16x+20) but wait they can be divided by 4?
----------- ----------
4 4 (Note if they can be divide by different numbers you can)
(4X+5)(4x+5) is the factor of it!
The GCF is 20x
If you mean: 4xsquared+40x+100 then divide all terms by 4 which then factors to (x+5)(x+5)
5x
The GCF is 20x.
40x(1-0.15)=40x0.85=34 34 is the answer
8 times(2x2 - 5x - 3) = 8(2x + 1)(x - 3)
4x+516x2 + 40x + 25= (4x + 5) (4x + 5)
X3 + 13X2 + 40X factor out an X X(X2 + 13X + 40) factor the quadratic expression, what two factors of 40 add up to 13? X(X + 8)(X + 5) works the same if that is a negative in front of X3, just sign changes
5x(6x + 7y + 8)
(2x+1)(2x+3) when factored
5x(7xy + 6x + 8)
(4x + 5)(4x + 5)
(x2 plus 40) (x minus 1)
16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
1/x + 2, provided x is not 0. If x is 0, the expression is undefined.
The factorization of 25x2 + 40x + 16 is (5x+4)(5x+4).
