1-150.

**Challenge:** Given: *ax*^{2} + *bx* + *c* = *d*(*x − e*)^{2} + *f*. Express *a*, *b*, and *c* in terms of *d*, *e*, and *f*. Homework Help ✎

The strategy is to distribute the right side so that has an *x*² term, an *x* term, and a constant expression.

Then you can match '*a*' to the constant with the *x*² term on the right, '*b*' to the *x* term on the right and '*c*' to the constant expression on the right.
