Q. Find the zeros of the function. Enter the solutions from least to greatest. f(x)=(x−5)(5x+2)
Set Function Equal to Zero: To find the zeros of the function, we need to set the function equal to zero and solve for x.f(x)=(x−5)(5x+2)=0We have a product of two factors equal to zero, which means that at least one of the factors must be zero.
Solve for First Factor: We set the first factor equal to zero and solve for x.x−5=0Adding 5 to both sides gives us:x=5
Solve for Second Factor: Now we set the second factor equal to zero and solve for x.5x+2=0 Subtracting 2 from both sides gives us:5x=−2 Dividing both sides by 5 gives us:x=−52
Identify Zeros: We have found the two values of x that make the function equal to zero. These are the zeros of the function.The zeros are x=5 and x=−52.We should now order these from least to greatest.
Order Zeros: Ordering the zeros from least to greatest, we get: x=−52 and x=5
