Give the values of a, b, and c from the general form of the equation (2x + 1)(x - 2) = 0.

When we expand this expression, we'll have a quadratic equation in the general form.

The general form of quadratic equations looks like this :



( a is coefficent of  , b is coefficient of x and c is the constant)

So let's expand the expression.



This how the final form of our equation :



As you can see  's coefficient (a) is 2 , x's coefficient (b) is -3 and the constant (c) is -2

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
