Zeroes are - 5 & - 2 of x² + 7x + 10
Step-by-step explanation:
Correct Question
x² + 7x + 10
= x² + 2x + 5x + 10
= x(x + 2) + 5(x + 2)
= (x + 5)(x + 2)
Zeroes are - 5 & - 2
Sum of Zeroes = - 5 - 2 = -7
Sum of Zeroes = - 7/1 = - 7
Verified
Product of Zeroes = (-5)(-2) = 10
Product of Zeroes = 10/1 = 10
Verified
