Answer:2x^2-5x-3
Step-by-step explanation:(2x + 1)(x - 3)
Multiply x and 2
Multiply x and 1
The x just gets copied along.
The answer is x
x
2*x evaluates to 2x
2*x+1 evaluates to 2x+1
x-3 evaluates to x-3
First, you multiply the two First terms, the 2x and x together.
Multiply 2x and x
Multiply the x and x
Multiply x and x
Combine the x and x by adding the exponents, and keeping the x, to get
The answer is x^2
Second, you multiply the two Outer terms, the 2x and -3 together.
Multiply 2x and -3
Multiply x and 1
The x just gets copied along.
The answer is x
x
2x × -3 = -6x
Third, you multiply the two Inner terms, the 1 and x together.
Multiply 1 and x
Multiply 1 and x
The x just gets copied along.
x
-6x combines with x to give -5x
Lastly, you multiply the two Last terms, the 1 and -3 together.
Multiply 1 and -3
1
1 × -3 = -3
(2*x+1)*(x-3) evaluates to 2x^2-5x-3
