Answer:
x= -3 x = 1/2 x=-2
Step-by-step explanation:
f(x)=(x+3) (2x-1)(x+2)
Set equal to zero
0 =(x+3) (2x-1)(x+2)
Using the zero product property
x+3 =0 2x-1 =0 x+2 =0
x= -3 2x =1 x = -2
x= -3 x = 1/2 x=-2
-3*10= -30 to the 4th power is 810,000
10 to the -3 power is -1000 * 2 is -2000
810,000 * -2000 = -1,620,000,000
10-7x=2-8x
We move all terms to the left:
10-7x-(2-8x)=0
We add all the numbers together, and all the variables
-7x-(-8x+2)+10=0
We get rid of parentheses
-7x+8x-2+10=0
We add all the numbers together, and all the variables
x+8=0
We move all terms containing x to the left, all other terms to the right
x=-8
If you translate this problem literally, it is saying, “72 is what percent of 288?”. And the equational translation of that is 72 = (x/100) • 288
[ “is” means equal to (=) // “what” means x or another variable // “percent” means divided by 100” // “of” means multiplication. ]
Then you solve that equation.
(you can check it by googling what is 25% of 288. )
