I am assuming you mean 3.0 *10^8 and 1.5 * 10^11.

16x-5y=-33 solve the equation

LUCKY_DIMON [66]

16x - 5y = -33 First, you subtract 16x from both sides of the
-16x -16x equation
-5y = -16x -33 Next, you divide both sides of the equation by -5 to
-5 -5 make "y =" form
y = 16/5x + 33/5

What is the factorization of the following trinomial? 15x2 - 44x - 36

BartSMP [9]

$15x^2-44x-36$

$=(15x^2+10x)+(-54x-36)$

factor out 5x from $15x^2+10x = 5x(3x+2)$

Factor out -18 from $-54x-36 = -18(3x+2)$

$=5x(3x+2)-18(3x+2)$

Factor out common term $(3x+2)$

$= (3x+2)(5x-18)$

hope this helps!
