Since the first and last terms are perfect squares, become suspicious and
test if it is perfect square.
sure enough, I get
(6f + 7)^2
Idk what to do?? Thanks for the help!
test if it is perfect square.
sure enough, I get
(6f + 7)^2
(6 f +/- 7) (6 f +/- 7) ???
oh my 6*7 = 42 and twice that is 84, we have it made
(6 f+7)(6 f+7)
You did not say what is on the right. If it is 0 then
f = -7/6, -7/6 and that is the vertex
now let's do that multiplication the long way
6 f (6 f + 7) + 7 (6 f + 7) = 6f *6f + 6f*7 + 6f*7 + 7*7
= 36 f^2 + 42 f + 42 f + 49
= 36 f^2 + 84 f+ 49
see that 42 f + 42 f = 84 f?
Step 1: Look for common factors, if any. In this expression, there are no common factors among the coefficients 36, 84, and 49.
Step 2: Check if it can be factored using a pattern. In this case, it cannot be factored using any common patterns.
Step 3: Factor the quadratic expression using the quadratic formula or by completing the square. However, this expression is not a quadratic expression in the standard form (ax^2 + bx + c), so these methods cannot be used.
Step 4: Since the expression cannot be further simplified through factoring, the expression 36f^2 + 84f + 49 is already in its simplest form.
Therefore, the simplified form of the expression 36f^2 + 84f + 49 is 36f^2 + 84f + 49 itself.
