43
Step-by-step explanation:
Using the remainder theorem, that is
The remainder on dividing f(x) by (x - h) is the value of f(h)
here division by (x - 3) hence evaluate f(3) for remainder
f(3) = 3² + 14(3) - 8 = 9 + 42 - 8 = 43 ← remainder
10a^3+277a^2-132a-792
step-by-step explanation:
(2a+11)(5a-12)(foil)
=10a^2-24a+55a-132 =10a^2+31a-132
(10a^2+31a-132)(a+6)
=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

the graph in the attached figure
we have
using a graphing tool
the roots are ( x-intercepts) x=-0.5,x=1,x=3
the y-intercept is the point (0,3)
