decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring. −b b2 − 4ac 2a u

Romashka [77]

Answer:

Step-by-step explanation:

A quadratic equation can be factorised if and only if there are rational roots.

For any quadratic equation the discriminant decides about the nature of roots.

Thus only if the discriminant is a perfect square we can have rational roots and in this case only factorization is possible.

In the given equation

$2x^2+ 7x+ 3 = 0\\a=2, b=7, c=3\\b^2-4ac = 1$

Since 1 is a perfect square we can factor and solve

$2x^2 +7x +3 = 0\\(2x+1)(x+3)=0\\x=-1/2 or x = -3$

Thor had a balance of -4$ in his savings account . After making a deposit , he has 25$ in his account . What is the overall chan

german

The equation to solve this would be:
-4+x=25
Solve for x.
Add 4 to both sides.
(-4+x)+4=(25)+4
x=29

The overall change to account was $29.

Hope this helps.

What would be the fraction of 1/2 = wht fraction of /8

kaheart [24]

Answer:

Number would be <u>4</u> to the fraction of $\frac{4}{8} =\frac{1}{2}$

Step-by-step explanation:

Given:

$\frac{1}{2}= \frac{\textrm{Number to find}}{8}\\\textrm{Number to find} =\frac{8}{2}=4$

Hence the Number would be 4 when it is divided 8 by we get the value as $\frac{1}{2}$ which is exactly what it is required so.

$\frac{1}{2}=\frac{4}{8}$
