You need to distribute the numerical factors for each term in the parenthesis:
This equals
Answer:
Step-by-step explanation:
3x² - 33x + 54 = 0
Divide the whole equation by 3
x²- 11x + 18 = 0
Sum = -11
Product = 18
Factors = -9 , -2 { - 9 + (-2) = -11 ; (-9) *(-2) = 18}
x² - 2x - 9x + -9 * -2 = 0
x(x - 2) - 9(x - 2) = 0
(x-2)(x-9) = 0
x - 2 = 0 ; x - 9 = 0
x = 2 ;x = 9
Lesser x = 2
greater x = 9
Answer:
(-4,6)
Step-by-step explanation:
When rotating 90 degrees counter clockwise you go from (x,y) to (-y,x)
First start by adding 2 to 4
then add 3 to 1
(6, 4)
then use the formula (-y,x) to change (6,4)
(-4,6)
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
Answer:
yes
Step-by-step explanation:
half of x which is 4 = y which is 2
you keep doing that with the rest of the xs and ys
