What is the value of coefficient c in this quadratic equation? 5x2 + 6x + 7 = 2(x + 2) a. 7 b. 4 c. 3 d. -3 e. 3/5

Step-by-step explanation:

C 3

Step-by-step explanation:

5x^2 + 6x + 7 = 2(x + 2)

Distribute the 2

5x^2 + 6x + 7 = 2x + 4

Subtract 2x from each side

5x^2+6x-2x +7 = 2x-2x+4

5x^2 + 4x + 7 = 4

Subtract 4 from each side

5x^2 +4x+7-4 = 4-4

5x^2 +4x+3 = 0

This is in the form ax^2 + bx +c  where c is 3

yes   because as the functions are graphed they eventually will intersect unless otherwise
