Please help i dn't know why my answer is wrong the area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. Find "a" if it is known that the parabola opens upward.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

the answer to that one is b

answer: 3 times more

step-by-step explanation: so the polar bear weighs 3 times more   than the black bear. so the grizzly weighs twice as much as the black bear. a good hint for word problems is to draw the problem out
