When we add or subtract polynomials, the addition or subtraction is applied to the coefficients of the terms of equal powers.
For the given polynomials, we are required to do subtraction as follows:
(-4.1 x^2 + 0.9 x - 9.8) - (1.7 x^2 - 2.4 x - 1.6)
= -4.1 x^2 + 0.9 x - 9.8 - 1.7 x^2 + 2.4 x + 1.6
= (-4.1-1.7) x^2 + (0.9+2.4) x + (-9.8+1.6)
= -5.8 x^2 + 3.3 x - 8.2
The final expression (solution) is:
-5.8 x^2 + 3.3 x - 8.2
Step-by-step explanation:
when applying a mathematical basic operation, we do this to the expressions of each function.
g(x) - f(x) = (x² + 5) - (4x - 7) = x² - 4x + 12

Answer:
DNE i think sorry if i am wrong
Step-by-step explanation:
EQUATION:
.4 + .3h = 2.5 Subtract .4 from each side
.3h = 2.1 Divide each side by .3
h = 7
