Question

Find the zeroes of the polynomial x*x+7x+10=0

Answer 1

Answer:

x= -5,-2

Step-by-step explanation:

x²+7x+10=0

Now take the factors of 10

5*2 = 10

2*5=10

10*1=10

If we add both factors, we must get 7 which is the coefficient of 'x' .

5+2=7

(x+5) (x+2)

x+5=0

x= -5

x+2=0

x= -2

Therefore zeroes of the polynomial is -5 and -2

if we substitute -5 or -2 in the above given equation we will get 0

xer of the polynomial = -5, -2
