Express the product of 2x squared + 7x - 10 and x + 5 in standard form

22x^2+7x-10 = x+5

2x^2+7x-15

y2x^2+6x-15


Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.


With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)

Write the equation of a line perpendicular to 3x+2y=6 through (2,-1).
iren [92.7K]
Rearrange: 2y = 6 -3x
2y = - 3x + 6
y = -1.5x + 3
Now, substitute, perpendicular lines have the same gradient so:
-1 = -1.5 (2) + c
- 1 = -3 + c
2 = c

equation for new line: y = 1.5x + 2
