Answer:
p=7x
Step-by-step explanation:
49x^[2] + 28x - 10 = p^[2] + 4p -10
This equation is in the form a^[2]x + bx + c.
The 'c' is common for both equations, this means the 'a' and 'b' must also be common.
There are two ways to find p: 'a' or 'b'
a method
49x^[2] = p^[2]
=> The square root of both sides = 7x = p
b method
28x = 4p
28x/4 = 4p/4
7x = p
