Solve h2-42 = -h using the quadratic formula. a) h = 0 or h = 7b) h = -6 or h = 7c) h = 6 or h= -7d) h = -6 or h = -7

Option C

h = 6 or h= -7

Step-by-step explanation:

We have the expression

To solve add h on both sides of the equality

For an equation of the form  the quadratic formula is

In this case

The answer is the option C

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
