Answer:
the coefficient of X2 is-4
the coefficient of X is-53
Step-by-step explanation:
given expression is
(X-3)(X+7)(X-8)
={X(X+7)-3(X+7)}(X-8)
={X2+7X-3X-21}(X-8)
={X2+4X-21}(X-8)
=X{X2+4X-21}-8{X2+4X-21}
=X3+4X2-21X-8X2-32X+168
=X3+(4X2-8X2)+(-21X-32X)+168
=X3-4X2-53X+168
the coefficient of X2 is -4
the coefficient of X is -53
