x² - 6x + 70 = 0 factorise
Answers
Answer
Simplifying
x2 + 6x + 70 = 0
Reorder the terms:
70 + 6x + x2 = 0
Solving
70 + 6x + x2 = 0
Solving for variable 'x'.
Begin completing the square.
Move the constant term to the right:
Add '-70' to each side of the equation.
70 + 6x + -70 + x2 = 0 + -70
Reorder the terms:
70 + -70 + 6x + x2 = 0 + -70
Combine like terms: 70 + -70 = 0
0 + 6x + x2 = 0 + -70
6x + x2 = 0 + -70
Combine like terms: 0 + -70 = -70
6x + x2 = -70
The x term is 6x. Take half its coefficient (3).
Square it (9) and add it to both sides.
Add '9' to each side of the equation.
6x + 9 + x2 = -70 + 9
Reorder the terms:
9 + 6x + x2 = -70 + 9
Combine like terms: -70 + 9 = -61
9 + 6x + x2 = -61
Factor a perfect square on the left side:
(x + 3)(x + 3) = -61
Can't calculate square root of the right side.
The solution to this equation could not be determined.
