Question

What should be added to 4x (x-3) to get 5x (x+4)

Answer 1

Answer:

x"2 +32x

Step-by-step explanation:

4x(x-3) +y=5x(x+4)

4x"2 -12x + y= 5x"2+20x

y=5x"2-4x"2+20x+12x

y=x"2+32x

Answer 2

◄███▓▒░░.ANSWER.░░▒▓███►

Let the added no. be = a

4x(x-3) + a = 5x(x+4)

4x² - 12x + a = 5x² +20x

a = (5x² - 4x²) + (20x + 12x)

$\bold{a \:= \:x^2\: +\: 32x}$

So $\bold{x^2 + 32x}$ should be added with 4x(x-3) to get 5x(x+4)
