Quadratic polynomial: y2 + 7y + 10
Formula used:
To find zeroes of ax2 + bx + c, use factor method: Find two numbers whose sum = b and product = c
Calculation:
We need two numbers whose sum = 7 and product = 10
Numbers are 5 and 2
So, y2 + 7y + 10 = (y + 5)(y + 2)
Zeroes are y = -5 and y = -2
∴ The zeroes of the polynomial are -5 and -2.
