Question

(8q2+4q+3)+(-5q2+2q-78)=​

Answer 1

Answer:

3(q² + 2q - 25)

Step-by-step explanation:

(8q² + 4q + 3) + ( - 5q² + 2q - 78)

Combining like terms.

= (8q² - 5q²) + (4q + 2q ) + (3 - 78)

= 3q² + 6q - 75

Taking 3 common.

= 3(q² + 2q - 25)

Well, the second stepp can be answer too if you don't want to factorize. But the factorized form is the standard one so better put it that way.

Answer 2

Correct Question :-

Solve — $ \rm{(8q^{2} + 4q + 3) + (-5q^{2} + 2q - 78)}$

Solution :-

Here, we can,

$\rm{(8 {q}^{2} + 4q + 3) + ( - 5 {q}^{2} + 2q - 78}$

$\to \rm{3q^{2}+4q+3+2q-78 }$

$\to \rm{3q^{2}+6q+3-78 }$

$\to \rm{3q^{2}+6q-75 }$

∴ Hence, the value for $ \rm{(8q^{2} + 4q + 3) + (-5q^{2} + 2q - 78)}$ will be $\rm{3q^{2}+6q-75 }$.
