Question

Standard form of 4-x²=5x

Answer 1

Answer:

$4 - x {}^{2} = 5x \\ = 2 {}^{2} - x {}^{2} = 5x \\ = > (2 + x)(2 - x) = 5x$

Answer 2

Step-by-step explanation:

4-x²=5x

(transpose 5x on the left side)

5x= -5x

-x²-5x+4 = 0

(remember that the number of a (-x²) should be positive)

We're gonna multiply them by -1

-x² x -1 = x²

-5x x -1 = +5x

+4 x -1 = -4

ANSWER: x²+5x-4=0
