Answer:
3⋅f(−4)−3⋅g(−2) = −12f+6g
Step-by-step explanation:
Write the problem as a mathematical expression.
3⋅f(−4)−3⋅g(−2)
Move − 4 to the left of f .
3⋅(−4⋅f)−3⋅(g(−2) )
Multiply−4 by 3.
−12f−3⋅(g(−2) )
Move − 2 to the left of g .
−12f−3⋅(−2⋅g)
and lastly Multiply−2 by −3.
−12f+6g
Hope this helps you out.
1) expand the brackets
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
simplify
-18 - 8x = 14
then add 18 to both sides to get the x's on there own
-8x = 32
then divide by -8
x = 32/-8
x = -4
2) multiply everything by 7x
2 + (6 x 7x) + ( 17x × 7x) = 18 x 7x
2 + 42x + 119x^2 = 126x
put everything on one side
119x^2 - 84x + 2 = 0
then use quadratic equation to solve
x = 0.024671849 or 0.6812105039
