Question

the coifficient of x^2 in 5x^2-a(3x^2 +5 )+4​

Answer 1

Step-by-step explanation:

5x² - a3x² - 5a + 4

= x²(5-3a) -5a + 4

coefficient of x² is (5-3a)

Answer 2

Answer:

5-3a

Step-by-step explanation:

5x^2-a(3x^2+5)+4

5x^2-3ax^2-5a+4

5-3a(x^2)-5a+4

Therefore, coefficient of x^2 is 5-3a
