A system of equations with one polynomial function of degree two and one linear function will have two solutions when the line intersects the parabola at two points.
A system of equations with one polynomial function of degree two and one linear function will have no solution when the line does not intersects the parabola.
A system of equations with one polynomial function of degree two and one linear function will have one solution when the line intersects the parabola at one point.
Answer:
<h2><em><u>(5a + 3b)(5a - 3b)</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
<em><u>Since</u></em><em><u>,</u></em>
<em><u>Then</u></em><em><u>,</u></em>
= <em><u>(5a + 3b)(5a - 3b) (Ans)</u></em>
Answer:
B
Step-by-step explanation:
For quadratic expression in this form, the first step is to multiply the number in front of with the last term, the constant (with the sign in front as well). This is the "multiplied number".
Step 2 is to come up with 2 numbers which when multiplied is equal to the "multiplied number" in step 1 above and also add to the number in front of .
For this problem, we would need 2 numbers that
- Add up to 27, and
- When multiplied, comes to -90 <em>(18 * -5 = -90)</em>
They already found the 2 numbers as expressed in the form shown . The 2 numbers are +32 and -5.
<em><u>Do they add up to 27, as required?</u></em>
Yes, 32-5=27
<u><em>Do they come to -90 when multiplied?</em></u>
No, 32 * -5 = -160
Hence, they add up, BUT NOT multiplied.
So the answer choice B is right.
