Question

How do you simplify x2−7x+12x2−25÷x−4x−5?

Answer 1

Step by step explanation :

$x2 - 7x + 12x2 - 25 \div x - 4x - 5$

Use the commutative property to reorder the terms.

$= > 2x - 7x + 12x \times 2 - 25 \div x - 4x - 5$

Calculate the product.

$= > 2x - 7x + 24x - 25 \div x - 4x - 5$

Write the division as a fraction.

$= > 2x - 7x + 24x - \frac{25}{x } - 4x - 5$

Collect like terms by calculating the sum or difference of their coefficients.

$= > 15 x - \frac{25}{x} - 5$

Write all numerators above the common denominator.

$= > \frac{15x {}^{2} - 25 - 5x }{x}$

Use the commutative property to reorder the terms.

$= > \frac{15x {}^{2} - 5x - 25 }{x}$
