To factor this equation... if you have learned before, find 2 numbers that add up to the middle value (-7) and multiply together to have a product of the last value (+10).
You can use guess and check for this problem... but if you haven't already found it... the sum of -5 and -2 is -7... and the product of -5 and -2 is +10, so we can use the values -5 and -2....
The solution is (c-5)(c-2) = c^2 - 7c + 10.

How do you find a constant k such that x minus 2 is a factor of x4 minus 5x3 plus kx2 plus 3x minus 10?
k = 7 x^4 - 5x^3 + 7x^2 + 3x - 10 = (x + 1)(x - 2)(x^2 - 4x + 5)
How do you factor a plus b quantity squared minus 100?
x2 + 100 has no real solutions. Applying the quadratic formula, we find two imaginary solutions: Zero plus or minus 10itimes the square root of 1.x = 10ix = -10iwhere i is the square root of negative 1.
What is 5x squared minus 23x minus 10 in factored form?
The correct factorization of 5 x plus 2 -3x x plus 2 is 2x+4.
Factor 2x2 plus 22x plus 8?
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 10 plus or minus 4 times the square root of 7. x = 20.583005244258363 x = -0.5830052442583629
How do you factor 3x2-2x-320?
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (-3 plus or minus the square root of 12329) divided by 2. x = 54.01801509420163 x = -57.01801509420163
