Question

factories
x2 - 55x + 750 =0​

Answer 1

Answer:

Step-by-step explanation:

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
