Question

If 49x2 + 28x - 10 is rewritten as p2 + 4p -10, what is p in terms of p=

Answer 1

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
