Let f(x)=4x^2+13x-12 and g(x)=x+4. Perform the function operation <br> F•g(x)<br><br> Please help!!!
ruslelena [56]

Answer: 4x³+29x²+40x-48

Step-by-step explanation:

To solve f(x)·g(x), you multiply them together.

(4x²+13x-12)(x+4)                           [distribute by FOIL]

4x³+16x²+13x²+52x-12x-48          [combine like terms]

4x³+29x²+40x-48

Now, we know that f(x)·g(x)=4x³+29x²+40x-48.

Determine the type and number of solutions of 4x^2-5x+1=0.
Arlecino [84]
<span>4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
</span>Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9
<span>
x = - b </span>± √Δ / 2.a
x =  \frac{-5\± \sqrt{9} }{2*4}
x =  \frac{-5\±3}{8}
x' =  \frac{-5-3}{8} =  \frac{-8}{8} = -1
x' = \frac{-5+3}{8} = \frac{-2}{8} (\div2) = \frac{-1}{4}


A. Two real solutions (x' = -1 and x'' = -1/4)
