Yes, a common denominator is just the smallest multiple of all numbers in a group.

So the common denominator of 4, 8 and 12 would be 4, because 4 goes into all those numbers.

Write a quadratic function h whose zeros are 5 and -7

marin [14]

Quadratic function whose zeros are 5 and -7 is x^2+2x-35=0

Step-by-step explanation:

Write a quadratic function h whose zeros are 5 and -7

If 5 and -7 are zeros of quadratic function then:

x=5 and x=-7

or x-5 = 0 and x+7=0

So, Finding quadratic equation:

$(x-5)(x+7)=0\\x(x+7)-5(x+7)=0\\x^2+7x-5x-35=0\\x^2+2x-35=0$

So, quadratic function whose zeros are 5 and -7 is x^2+2x-35=0
