Factoring a trinomial using the diamond method

The video tutorial explains how to solve a quadratic equation by identifying coefficients and using factorization. It covers the quadratic form AX^2 + BX + C, finding factors that multiply to a given number and add to another, and concludes with the FOIL method to verify the solution.

What is the standard form of a quadratic equation?

• AX^2 + BX + C

• AX + B = C

• AX + BX^2 + C

• AX^2 + B = C

If a product of two numbers is negative, what can be said about the signs of the numbers?

• One number is positive and the other is negative

• Both numbers are positive

• Both numbers are zero

• Both numbers are negative

Which pair of numbers multiplies to -56 and adds to 1?

• 8 and -7

• 14 and -4

• 28 and -2

• 7 and -8

When rewriting a quadratic equation as two binomials, what method is used to verify the solution?

• Graphing method

• Elimination method

• Substitution method

• FOIL method

What is the result of multiplying W + 8 and W - 7?

• W^2 + W - 56

• W^2 - 15W + 56

• W^2 - W + 56

• W^2 + 15W - 56
