note that the zeroes should be x = 1 and x = - 2 not x = - 1 and x = 2
the factors are then ( x - 1 ) and (x + 2)
and x³ - 4x² - 7x + 10 = (x - 1 )(x + 2) = x² + x - 2
thus x² + x - 2 is a factor
dividing x³ - 4x² - 7x + 10 by x² + x - 2 gives x - 5
the third zero is x = 5
check : (5)³ -4(5)² - 7(5) + 10 = 125 - 100 - 35 + 10 = 0
A = 7
b = -18
c = -52
Do you know what the Quadratic formula is to solve?
Answer: -5 < x + 1 < 3
Step-by-step explanation:
Let x be the number.
-5 < x + 1 < 3
Answer:
0.15
Step-by-step explanation:
9.70-8.95= 0.75
0.75÷5= 0.15
The equation is asking to calculate the standard for of the equation of ellipse satisfying the given condition and in my further research and computation, would say that the answer would be <span>x^2/21 + y^2/25 = 1. I hope you are satisfied with my answer and feel free to ask for more</span>
