Which statement about y = x2 + 7x - 30 is true? A. The zeros are -3 and 10, because y = (x + 3)(x - 10).
B. The zeros are 3 and -10, because y = (x+3)(x - 10).
C. The zeros are – 3 and 10, because y = (x - 3)(x+ 10).
O D. The zeros are 3 and -10, because y = (x - 3)(x + 10).

D. The zeros are 3 and -10, because y = (x - 3)(x + 10).

Step-by-step explanation:

Therefore, D is correct by the Zero Product Property

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
