Answer:
x³ - 10x² + 31x - 30
Step-by-step explanation:
Given
(x - 2)(x - 3)(x - 5) ← expand the second pair of factors using FOIL
= (x - 2)(x² - 8x + 15) ← distribute
= x³ - 8x² + 15x - 2x² + 16x - 30 ← collect like terms
= x³ - 10x² + 31x - 30
Answer:
Yeah,its right angled traingle.
Reason:Suppose Root over 50 as hypotenuse and other two sides as base and perpendicular respectively.
By using pythagoras theorem
h^2=p^2+b^2
50=50(which is true)
Therefore it is right angled triangle..This is your required answer.
