Whats the expression y^2+7y+12

Mathematics

We can find the value of y in the expression y<span>² + 7y + 12 by factorising.


Make the expression equal to zero.

y</span><span>² + 7y + 12 = 0


Factorise.

(y + 3)(y + 4) = 0


So either (y + 3) = 0 or (y + 4) = 0


When (y + 3) = 0, y would be -3.

When (y + 4) = 0, y would be -4.</span>
