The factorization of 25x2 + 40x + 16 is (5x+4)(5x+4).
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
well its impossible to answer since there is no x=? if it was 5x+20=40 then x=4 5 x 4=20+20=40
2x2 - 5x + 12 does not factor. 2x2 - 5x - 12 factors into (2x + 3)(x - 4) 2x2 + 5x - 12 factors into (2x - 3)(x + 4)
5X + 25 = 20 subtract 25 from each side 5X + 25 - 25 = 20 - 25 5X = - 5 divide both side integers by 5 X = - 1 check 5(-1) + 25 = 20 - 5 + 25 = 20 20 = 20 checks
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
The factors of x2 + 5x + 4 would be (x + 1) and (x + 4)
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
Since 5x + 20 is a multiple of x + 4, it is automatically the LCD of this problem.
The factorization of 25x2 + 40x + 16 is (5x+4)(5x+4).
That expression is the square of (5x + 1), so both of its factors are the same.
It is: -5x-20 when simplified
5x+3 = -17 5x = -17-3 5x = -20 x = -4
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
x2 - 5x + 6 = (x - 2)(x - 3)
