(x+7)(x+12)

(x - 10)(x - 9)

(x - 12)(x - 7)

That's not a trinomial, but it factors to x(x + 19)

Factor as : (x+9)(x+10) using the first terms ( x terms) multiply to x2; the last terms multiply to 90; the sum of 9x + 10 x = 19x

19x

x(x - 19)(x - 1)

X2 + 19X - 42 = 0What two factors of - 42 add up to 19?(X - 2)(X + 21)----------------------FOIL and see the function reappear.X = 2X = - 21

x=-2

(x - 3)(7x + 2)

(x - 4)(5x + 1)

(3x + 7)(x + 4)

Divide by x: x(x2 - 20x + 19); = x(x -1)(x - 19)

use the quadratic formula since there isn't a factor of 60 that when added together equals 19 The above answer is wrong because 4 and 15 are such numbers. x2 + 19x + 60 = x2 + 4x + 15x + 60 = x(x + 4) + 15(x + 4) = (x + 4)(x + 15)

That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 3 plus or minus the square root of 19x = 7.358898943540674x = -1.358898943540674

6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2

Since 19x^3 is a factor of 38x^5, it is automatically the GCF.

8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2

no one can do that. it doesn't make scence

-15

19x+1x+37=0 First add the 19x and 1x together 20x+37=0 Next subtract 37 to the other side 20x=-37 Now divide both sides by 20 x=-20/37

The GCF is x5

-11
