Question

is it true that the zeroes of the quadratic polynomial
${x}^{2} + 35x + 300$
are both negative
​

Answer 1

Answer:

yes

Step-by-step explanation:

upon solving we get

x^2+35x+300

x^2 +20x+15x+(15×20)

(X+15)(X+20)

therefore X=-15 and -20 ( both are negative)

Answer 2

x^2+35x+300=0

has both negative zero

x^2+20x+15x+300=0

X(X+20)+15(X+20)=0

(X+15)(X+20)=0

X+15=0. X+20=0

X= -15. X= -20
