Factor completely. -5h^4-15h^3-10h^2

-5h^4-15h^3-10h^2
= -5h^2(h^2 + 3h + 2)
= -5h^2(h+2)(h+1)

Simplifying g2 = 13 + -12g Solving g2 = 13 + -12g Solving for variable 'g'. Reorder the terms: -13 + 12g + g2 = 13 + -12g + -13 + 12g Reorder the terms: -13 + 12g + g2 = 13 + -13 + -12g + 12g Combine like terms: 13 + -13 = 0 -13 + 12g + g2 = 0 + -12g + 12g -13 + 12g + g2 = -12g + 12g Combine like terms: -12g + 12g = 0 -13 + 12g + g2 = 0 Factor a trinomial. (-13 + -1g)(1 + -1g) = 0 Subproblem 1Set the factor '(-13 + -1g)' equal to zero and attempt to solve: Simplifying -13 + -1g = 0 Solving -13 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + -1g = 0 + 13 Combine like terms: -13 + 13 = 0 0 + -1g = 0 + 13 -1g = 0 + 13 Combine like terms: 0 + 13 = 13 -1g = 13 Divide each side by '-1'. g = -13 Simplifying g = -13 Subproblem 2Set the factor '(1 + -1g)' equal to zero and attempt to solve: Simplifying 1 + -1g = 0 Solving 1 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1g = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1g = 0 + -1 -1g = 0 + -1 Combine like terms: 0 + -1 = -1 -1g = -1 Divide each side by '-1'. g = 1 Simplifying g = 1Solutiong = {-13, 1}

lol srry this should be the answer you are looking 4 hope this helps

-8x + 3y = 21
-8x + 8x + 3y = 21 + 8x
3y = 21 + 8x
 3          3
  y = 7 + 2 2/3x
-8x + 3(7 + 2 2/3x) = 21
-8x + 21 + 8x = 21
-8x + 8x + 21 = 21
0x + 21 = 21
0x + 21 - 21 = 21 - 21
0x = 0
 0     0
  x = 0
-8(0) + 3y = 21
0 + 3y = 21
3y = 21
 3      3
  y = 7
(x, y) = (0. 7)

-8x + 3y = 21
-8x + 3y - 3y = 21 - 3y
-8x = 21 - 3y
 -8         -8
   x = -2 5/8 + 3/8y
-8(-2 5/8 + 3/8y) + 3y = 21
21 - 3y + 3y = 21
21 - 0y = 21
21 - 21 - 0y = 21 - 21
-0y = 0
