Answer:
D
Step-by-step explanation:
If those two functions are the factors of a quadratic, then each of them can be equated to 0 to find the roots. Sometimes the roots are called the zeros.
2x - 5 = 0 Add 5 to both sides
2x - 5 + 5 = 0 + 5 Combine
2x = 5 Divide both sides by 2
2x/2 = 5/2
x = 5/2
You don't really have to find the other factor's 0 point. There is only 1 option that makes x = 5/2. On a test, it is important to take short cuts and save time. I'll find the other root anyway because this is not a test.
3x + 4 = 0 Subtract 4 from both sides
3x + 4-4 = 0 - 4 Combine
3x = - 4 Divide both sides by 3
3x/3 = - 4/3
x = - 4/3

SO C.45
Hello there,
Well we are given with 3(x + 4)² and we need to simplify this expression...
- write out the expression: 3(x + 4)(x + 4)
- then we distribute the parentese: 3(x² +4x +4x +16)
- combine like terms: 3(x² + 8x + 16)
- distribute the 3 in the parentese: 3x² + 24x + 48
So another way to express this would be 3x² + 24x + 48.
Hope I helped,
Amna
