How do you factor x squared minus 10x minus 24?

10x2 + 3x - 4 = (5x + 4)(2x - 1)10x2 + 3x - 4When dealing with quadratic expressions the standard form is ax2 + bx + c.The factor format is (mx + n)(px + q). In this question a = 10, b = 3, c = -4.The technicalities can be covered later but basically combine the product of the factors of a with those of c so that the sum generates the value of b.As a = 10 the factors are 10 x 1 or 5 x 2 (In all cases the reverse signage may apply e.g. -10 x -1 or -5 x -2)As c = -4 the factors are -4 x 1, -2 x 2 (and reverse signage if relevant)10 x -4 and 1 x 1 OR 10 x 1 and 1 x -4 do not generate 3.5 x -4 and 2 x 1 does not provide the solution but 5 x 1 and 2 x -4 does generates -3 which the reverse signage to 3. So by making the calculation 5 x -1 and 2 x 4 the desired result is achieved.The factors are thus (5x + 4)(2x - 1)...........note that the pairs of numbers in the calculation process separate when placed in the brackets /parentheses.


What is a factor of 20x2-39x plus 18?

10x2-36x+18 Divide all terms by 2: 5x2-18x+9 = (5x-3)(x-3) when factored


How do you factor the cubic polynomial 4x3 plus 20x2 plus 2x-3?

This polynomial doesn't factor. The only thing you can do is take out parts of some terms, e.g. 2(2x3 + 10x2 + x) - 3.


How do you write out a factor pair?

Factor pairs are any two numbers being multiplied to give you a certain number. Examples for 20: 1x20, 20x1, 2x10, 10x2, 4x5, and 5x4 are all factor pairs for 20.
