Mathematics
1 answer:
Vinil7 [7]3 years ago
7 0

Step-by-step explanation:

-5x+8y=-4

6x-8y=-12   8y and 8x cancel out

         x=-16

To solve for y, substitute x=-16 back into the first equation

-5(-16)+8y=-4

    80+8y=-4

          8y=-84

            y=-10.5

Factorize by grouping: <br>4pº + 8p2 + 3p + 6​
Nastasia [14]
<h3>Answer:  (4p^2+3)(p+2)</h3>

Work Shown:

I'm assuming you meant to write 4p^3+8p^2+3p+6

If so, then we would have these steps

4p^3+8p^2+3p+6

(4p^3+8p^2)+(3p+6)

4p^2(p+2)+3(p+2)

(4p^2+3)(p+2)
