Use pemdas : so do parenthesis first 15-8, then multiply the answer by 6. OR u can use distributive property & multiply 6 by 15 & 8
Answer:
x³-9x²+14x+24
Step-by-step explanation:
here given : 4, -1, 6
so put negative value of each digit in the equation
(x-4)(x+1)(x-6)
(x²-4x+x-4)(x-6)
(x²-3x-4)(x-6)
(x³-3x²-4x-6x²+18x+24)
x³-9x²+14x+24
-3√45 + 3√20 = -3√(9 · 5) + 3√(4 · 5) =
= -3√(3² · 5) + 3√(2² · 5) =
= -3 · 3√5 + 3 · 2√5 =
= -9√5 + 6√5 = -3√5 ← the end
