What is the expression in factored form x^2+13x+42 i got (x+6)(x+7) by doing 13=6+7 & 42=6x7

we have

Find the factors

Equate the equation to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side

Rewrite as perfect squares

Square root both sides

therefore

the answer is

the answer is c

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
