2x2-3x-5
is that 2x^2-3x-5?
5-2 = 3 so we can factor it
(2x-5)(x+1)
To evaluate the expression 2x2 - 3x - 5, you can follow these steps:
Step 1: Multiply the coefficient of x2 (which is 2) by the value of x2.
2x2 = 2 * x * x = 2x^2
Step 2: Multiply the coefficient of x (which is -3) by the value of x.
-3x
Step 3: Add the results of the previous two steps.
2x^2 - 3x
Step 4: Subtract 5 from the result obtained in Step 3.
2x^2 -3x - 5
Therefore, the simplified expression is 2x^2 - 3x - 5.
