Simplify \(\frac{2x-1}{3}-\frac{x+3}{2}\)
\(\frac{x+3}{6}\)
\(\frac{x+8}{6}\)
\(\frac{x-11}{6}\)
\(\frac{x-4}{6}\)
Correct answer is C
\(\frac{2x - 1}{3} - \frac{x + 3}{2}\)
= \(\frac{2(2x - 1) - 3(x + 3)}{6}\)
= \(\frac{4x - 2 - 3x - 9}{6}\)
= \(\frac{x - 11}{6}\)
(6x - 5)(x + 4)
2(3x-5)(x+2)
(3x+4)(2x-5)
(3x-4)(2x+5)
Correct answer is D
\(6x^2 + 7x - 20\)
= \(6x^2 + 15x - 8x - 20\)
= \(3x(2x + 5) - 4(2x + 5)\)
= \((3x - 4)(2x + 5)\)
