1.)

${x}^{2} + 20 = 9x$

${x}^{2} + 20 - 9x = 0$

${x}^{2} - 9x + 20 = 0$

${x}^{2} - 4x - 5x + 20 = 0$

$x(x - 4) - 5(x - 4) = 0$

$x - 5 = 0 \\ x - 4 = 0$

$x = 5 \\ x = 4$

The problem has two possible answers

X1 = 5
X2 = 4

2.)

$x \times (x + 1) = 56$

${x}^{2} + x = 56$

${x}^{2} + x - 56 = 0$

${x}^{2} + 8x - 7x - 56 = 0$

$x(x + 8) - 7(x + 8) = 0$

$x - 7 = 0 \\ x + 8 = 0$

$x = 7 \\ x = - 8$

The problem says that the consecutive integers must be positive, x = 7

$x = 7 \\ x + 1 = 8$

The two consecutive positive integers are 7 and 8 with a product of 56

SecretSwallowtail thankyouuuuu

MathLord69 ung sa 4th step ng solution kailangan maghanap ka ng factors ng C na ang sum ay ung b

MathLord69 sa number 1

MathLord69 -9x + 20

MathLord69 -4x - 5x ung factors kasi -4 x -5 = +20 and -4 + (-5) = -9
