Subtract 3x squared +7x-4 from 8x squared-6+2 your answer should be polynomial in standard form

5x² - 13x + 6

Step-by-step explanation:

8x² - 6x + 2 - (3x² +7x -4)

Simplify the expression:

8x² - 6x + 2 - 3x² -7x + 4

Combine like terms:

5x² - 13x + 6

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
