What is the sum of the roots of the equation 2x2-13x plus 17 equals 0?
6.50 to the nearest hundredth (4.685 & 1.815)
Which is more the sum of 4 and 5 or the product of 4 and 5?
the product of 5x4 because 5x4=20 and 5+4=9
What two numbers have a product of 20 and a sum of 9?
5 and 4. 5x4=20 (product) 5+4=9 (sum)
Can the sum of two polynomials with x as the variable both starting as degree 4 simplify to be of degree 3 in the answer?
Yes. Here is an example: P1 = 5x4 + 3x3; P2 = -5x4 -2
What is Three times a number plus ten times the quantity of the sum of a number and four is one hundred seventy.?
Let the number be represented by ( x ). The equation can be written as ( 3x + 10(x + 4) = 170 ). Simplifying this, we have ( 3x + 10x + 40 = 170 ), which combines to ( 13x + 40 = 170 ). Subtracting 40 from both sides gives ( 13x = 130 ), leading to ( x = 10 ).

Factor the trinomial x2 plus 13x plus 40?
You should look for two numbers whose product is 40, and whose sum is 13. Experimenting a little (trying different pairs of factors for 40), you can quickly realize that this works for 8 and 5. Therefore, x2 + 13x + 40 = (x + 8) (x + 5)
What is Three times a number plus ten times the quantity of the sum of a number and four is one hundred seventy.?
Let the number be represented by ( x ). The equation can be written as ( 3x + 10(x + 4) = 170 ). Simplifying this, we have ( 3x + 10x + 40 = 170 ), which combines to ( 13x + 40 = 170 ). Subtracting 40 from both sides gives ( 13x = 130 ), leading to ( x = 10 ).
What are the factors of this quadratic trinomial 12x2 plus 13x 35?
12x2+13x-35 = (4x-5)(3x+7) 12x2 + 13x- 35 let's find two factors of -420 (12*-35) whose sum is 13, which are 28 and -15 (12x + 28)(12x - 15) now simplify by 4 and 3 (3x + 7)(4x - 5)
What is substitution for math?
When you check an answer by using it in another sum e.g2x+7=13x=3substitute to second-4x+6=18x=3 which is correct
