\large \mathfrak{Solution : }

f (x) = x² + 5x

g (x) = 3x² - 4x

f (x) * g (x) :

  • ( {x}^{2}  + 5) \times (3 {x}^{2}  - 4x)

  • 3x {}^{4}  - 4 {x}^{3}  + 15 {x}^{2}  - 20x

Step-by-step explanation:

f(x) × g(x)

= (x2 + 5x )× (3x2 -4x )

=3x4 + 15x3 - 4x3 -20x2

3x^4 + 11 x3 - 20x2

What is the solution for the system of equations {9x+8y=3 6x−12y=−11?
lions [1.4K]

Answer:

( - \frac{1}{3}, \frac{3}{4} )

Step-by-step explanation:

Given the 2 equations

9x + 8y = 3 → (1)

6x - 12y = - 11 → (2)

To eliminate the y- term multiply (1) by 1.5

13.5x + 12y = 4.5 → (3)

Add (2) and (3) term by term

(6x + 13.5x) + (- 12y + 12y) = (- 11 + 4.5)

19.5x = - 6.5 ( divide both sides by 19.5 )

x = \frac{-6.5}{19.5} = - \frac{1}{3}

Substitute this value into either of the 2 equations and solve for y

Using (1), then

- 3 + 8y = 3 ( add 3 to both sides )

8y = 6 ( divide both sides by 8 )

y = \frac{6}{8} = \frac{3}{4}

Solution is (- \frac{1}{3}, \frac{3}{4} )
