Question

X2-55x+750=0 quardratic equarion

Answer 1

Answer:(x-25)(x-30)

Step-by-step explanation:

x^2 -55x +750

= x^2 -25x -30x +750

= x(x-25) -30(x-25)

= (x-30)(x-25)

Answer 2

x² - 55x + 750 = 0

By splitting the middle term

➾ x² - 25x - 30x + 750 = 0

Factor the expressions

➾ x(x - 25) - 30(x - 25) = 0

Factor the expression

➾ (x - 25) (x - 30) = 0

Split into possible cases

➾ x - 25 = 0

x - 30 = 0

Solve the equations

➾ x = 0 + 25

x = 0 + 30

➾ x = 25

x = 30


The final solutions are :

$x_1\:=\:25\:,\:x_2\:=\:30$
