can you make it so it doesn't look copy n pasted thanks im in a hurry.

Answer 1

Also
What are the x- and y-intercepts of the graph of y = 2x2 + 4x - 6?

x-intercepts: (1, 0) and (-3, 0)
y-intercept: (0, -3)
x-intercepts: (1, 0) and (-3, 0)
y-intercept: (0, -6)
x-intercepts: (-1, 0) and (3, 0)
y-intercept: (0, -3)
x-intercepts: (-1, 0) and (3, 0)
y-intercept: (0, -6)
3. Solve. x2 + x = 20

x = 5 and x = -4
x = 5 and x = 4
x = -5 and x = -4
x = -5 and x = 4
4. Solve 5x2 + 25x = 180.

x = 4 and x = -9
x = 4 and x = 9
x = -4 and x = -9
x = -4 and x = 9

Answer 3

I honestly just want the first question.

Answer 4

Does it look like it factors? If not, graphing would be hard, so competing the square or quadratic would be the next choice.

Answer 5

completing the square would be the easiest way to do it
