Question

sum of 4 + 3 and 5 - 4 x + 2 x square is the sum of three square - 5 x and x square + 2 X + 5​

Answer 1

Answer:

x = {1 , -2}

Step-by-step explanation:

If you are saying,

(4 + 3) + (5 - 4x + 2x^2) = (3^2 - 5x) + ( x^2 + 2x + 5)

Then ,

7 + 2x^2 - 4x + 5 = 9 - 5x + x^2 + 2x + 5

2x^2 - 4x + 12 = x^2 - 3x + 14

x^2 - x - 2 = 0

Solving the given equation , we get

x = {1 , -2}
