Question

y2- y- 72. Find all the zeros and verify

Answer 1

Step-by-step explanation:

Using the factorization method.

we can write this equation as

y2 - 9y + 8y -72 = 0;

now taking y and 9 as comMon and making the similar factor;

y(y-9) + 8(y-9) = 0;

(y-9) ( y+8) = 0;

now equating both the factors with zero;

y-9 = 0;

y = 9; and y+8 = 0;

y = -8;

so 9 and -8 are the zeros of that given equation. for verification if we put y = 9 in the equation y2-y-72 we get the result is zero;
