To find two numbers that add up to 45 and multiply to -196, we can set up a system of equations. Let's call the two numbers x and y. We have the equations x + y = 45 and x * y = -196. By solving these equations simultaneously, we can find that the two numbers are 13 and -15, as 13 + (-15) = 45 and 13 * (-15) = -196.
What else can I help you with?
Mean how do you find the mean of a set of numbers?
What you have to do is you add up all the numbers then you divide by the number of numbers. ex. Say you have the numbers 45,56,39 and 35 you add them all up 45+56+39+35=175 then you divide 175/4(because there is 4 numbers)=43.75
How do you add area of a semicircle and area of a rectangle?
Simply add the numbers up For example, If the area of a semicirce is 20cm squared and the area of a rectange is 25cm squared, then the total area would be 20 + 25 = 45

What are the numbers that you can multiply together to get 450?
Well, isn't that a happy little math problem! To find the numbers you can multiply together to get 450, we want to think about factors. You could multiply 15 and 30 together, or 10 and 45, or even 5 and 90. There are many possibilities, so just explore and see what makes you smile!
What is the sum of 13 17 15?
Oh, dude, you're hitting me with some math? Okay, let me put on my thinking cap... So, if we add 13, 17, and 15 together, we get... drum roll, please... 45! Like, it's not rocket science, but hey, I did the math for you. You're welcome.

What 2 numbers add up to -45 and multiply to -196?
1) x + y = -45 2) xy = -196 solve for x in equation 2 by dividing both sides by y x= -196/y plug this value for x into the first equation -196/y + y = -45 subtract y from both sides -196/y = -45-y multiply both sides by -y 196 =45y + y2 subtract 196 from both sides 0 = y2 + 45y - 196 factor 0 = (y + 49)(y - 4) set each factor equal to 0 y + 49 = 0, y = -49 y - 4 = 0, y = 4 y = -49 or 4 plug these values back into equation 1 x + 4 = -45, x = -49 x + -49 = -45, x = 4 so the two numbers are 4 and -49 As two numbers are required that sum to -45 and multiply to -196, start off by working out the prime factorization of 196: 196 = 2 x 2 x 7 x 7. Using this, pairs of factors of 196 can be calculated: 1 x 196 2 x 98 4 x 49 7 x 28 14 x 14 As -196 is required, one factor must be positive and the other negative which means when they are summed, really their difference is calculated: 1 x 196 - difference = 195 2 x 98 - difference = 96 4 x 49 - difference = 45 7 x 28 - difference = 21 14 x 14 - difference = 0 A difference of 45 means the factors are 4 and 49, but as -45 is required, the larger factor must be negative, meaning the required numbers are 4 and -49 If you are in fact trying to factor a quadratic equation x2 - 45x - 196 = 0, you could also use the quadratic formula [-b + or - the square root of (b2-4ac)] / 2a so [-(-45) + or - the square root of ((-45)2 - 4(1)(-196)] / 2(1) [45 + or - square root of (2809)] / 2 [45 + or - 53] / 2 45 + 53 = 98, divide by 2 = 49 45 - 53 = -8, divide by 2 = -4 so the roots are (x - 49)(x + 4) so x = {49, -4}
