Q. Perform the following operation and express in simplest form.x2−64x2⋅x−2x2−10x+16Answer:
Factor Quadratic Expressions: Factor the quadratic expressions where possible.The denominator x2−64 is a difference of squares and can be factored as (x+8)(x−8).The numerator x2−10x+16 can be factored as (x−2)(x−8) because it is a quadratic expression that factors neatly.
Write Factored Expression: Write the expression with the factored forms.The expression now looks like this:(x+8)(x−8)x2×x−2(x−2)(x−8)
Cancel Common Terms: Cancel out the common terms.The (x−8) term in the numerator and denominator cancels out, as does the (x−2) term.This leaves us with:(x+8)x2
Check Further Simplification: Check for any further simplification.The expression x+8x2 cannot be simplified further because x2 is not a multiple of x+8.
