Step-by-step explanation:
Standard polynomial is:
Leading co effecient is:
-20
3/4x-12-5=15
3/4x-17=15
3x-68=60
3x=60+68
3x=128
X=128/3
0.4%, turn it into a decimal, which is 0.004
0.004*100= 0.4
Hello there!
To find the zeroes or the roots of a function, you just need to set the function equal to 0 then solve for x
f(x) = 2x² - 8x - 10
Set function equal to 0
2x² - 8x - 10 = 0
Now we can factorize the left side
2(x + 1)(x - 5) = 0
Then set factors equal to 0
x + 1 = 0 or x - 5 = 0
x = 0 - 1 or x = 0 + 5
x = -1 or x = 5
Thus,
The roots are -1 and 5
