Difference of Cubes Theorem
8x^3 - 27 Factors to (2x - 3)(4x^2 + 6x +9)
Step-by-step explanation:
a)x + 4 + 2x +5
= x + 2x + 4 + 5
<h3>= <u>3x + 9</u></h3><h3 /><h3>b)10x - 3x + 7</h3><h3>=7x + 7</h3><h3 /><h3>c)5x + 6y + 2xy + 4x - 2y</h3><h3>=5x + 4x + 6y - 2y + 2xy</h3><h3>=9x + 4y + 2xy</h3><h3>c)7t + 2r - 3t + r</h3><h3>=7t - 3t + 2r + r</h3><h3>=4t + 3r</h3><h3 /><h3>d)14 + 11p - 12</h3><h3>=14 - 12 + 11p</h3><h3>=2 + 11p</h3><h3 /><h3>e)8q - 3t + 4q + 9</h3><h3>=8q + 4q + 3t + 9</h3><h3>=12q + 3t + 9</h3><h3 />
The sum of any two rational numbers is rational. Both of these numbers are rational, therefore adding them will give us another rational number.
