Answer:
It is.
Step-by-step explanation:
1. Multiply 2x *x and 2x* -3 ;
2. Multiply 1*x and 1*(-3) ;
You should get: 2x^2 -6x +x -3 = 2x^2 -5x -3;
3. Add -6x +x;
In the end you get : 2x^2 -5x -3=2x^2 -5x -3
Answer:
Step-by-step explanation:
Use FOIL:
(a + b)(c + d) = ac + ad+ bc+ bd
(2x + 1)(x - 3)
= (2x)(x) + (2x)(-3) + (1)(x) + (1)(-3)
= 2x² - 6x + x - 3 combine like terms
= 2x² + (-6x + x) - 3
= 2x² - 5x - 3
