2013年3月11日 · x-3| x^2+5x-28 start by seeing how many times the first coefficient will go into the first term of the polynominal -(x^2 -3x) multiply x-3 by x and subtract the first and second terms. 8x-28 repeat until you are at the end of the polynominal

2018年11月3日 · Karl S. 21 and 7. Their sum is: 21 + 7 = 28 and their quotient is: 21 / 7 = 3. To find them use: x + y = 28 and x/y = 3 Thus: x = 3y, 3y + y = 28, 4y = 28, y = 7, x = 21

2017年9月25日 · Factor. 49x^2 − 28x + 3. Log in Sign up. Find A Tutor . ... = -28 bingo! then, write: 49x^2 -28x + 3 ...

x = (28 - 27.785) / -2 and x = (28 + 27.785) / -2 x = -0.108 and x = -27.893 Substitute these x values into eq2 to solve for y.

2013年1月31日 · Factors of 28: 1·28, 2·14, 4·7. Factors of 2: 1·2. Since the only set of factors for 2 are 1 and 2, we arrive at the following: x(28x 2 + 15x + 2) = x( + 1)( + 2) It is obvious that if we try to use 1 and 28 to factor 28, the sum of the products will be much greater than 15. Likewise, 2 and 14 will also yield a sum larger than 15.

write 2 equations for a polynomial whose graph has x-intercepts at x= -3, -1, and 5; The sum of three prime numbers is 100.one of them exceeds the other by 24.what are the three no, s. At the movie theater, child admission is $6.30 and adult admission is $9.70. On Saturday, 130 tickets were sold for a total sales of $1080.80.

Lara T. asked • 12/07/15 One of the legs of a right triangle is twice as long as the other, and the perimeter of the triangle is 28.

For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x – 1). Order of Operations
