Step-by-step explanation:
Simplify step-by-step.
8y+10−4−5y
=8y+10+−4+−5y
Combine like terms:
=8y+10+−4+−5y
=(8y+−5y)+(10+−4)
=3y+6
Number 2 is 84.13
number 4 is 56
Step-by-step explanation:
f(x) = x³ + 3x² - x - 3 = x²(x + 3) - (x + 3)
= (x² - 1)(x + 3) = (x + 1)(x - 1)(x + 3).
The roots of f(x) are x = -3, -1 and 1.
=> The new roots are x = -5, -3 and -1.
=> g(x) = (x + 5)(x + 3)(x + 1) = x³ + 9x² + 23x + 15.
