First off, do a prime factoring of the constant and leading coefficient, namely 9 and 8 respectively.
so a prime factoring of 8 is 2*2*2, and a prime factoring of 9 is 3*3.
so, those are the factors... now, how do we produce products that gives us the middle coefficient +18?
well, let's see hmmmm 2 * 3 * 3 and 2 * 3....so that's 18 + 6, that's 24.. .so... no good is not 18, let's try again.
2*2*3 and 2 * 3, so that's 12 + 6, now, that's +18
so we'll use those, 2*2*3 and 2*3, or 4 * 3 an 2 * 3, (4x + 3)(2x + 3) = 0.
Step-by-step explanation:
4x² + 11x - 3 = 0
(4x-1)(x+3) = 0
x = 1/4, -3

we sniled it to the lete by 2 and then we snifted it down by
Answer/Step-by-step explanation:
1. ; 3
Let's solve for a.
(subtraction property of equality)
(division property of equality)
Therefore, 3 is a solution to 9 = 2a + 3
2. ; 7
(- × - = +)
(Subtraction property of equality)
(division property of equality)
Therefore, 7 is not a solution of
3. ; 1
Therefore, 1 is a solution of .
