Question

Simplify (3x^2+4x-3)-(4x^2-3x+2)

Answer 1

−x^2+7x−5

Step-by-step explanation:

times this by 1 (3x^2+4x−3) −(4x^2-3x+2) ---- times this by - 1

3x^2+4x−3−4x^2+3x−2

3x^2+4x−3−4x^2+3x−2 - collect like terms

(3x^2+−4x^2)+(4x+3x)+(−3+−2) - solve it

(3x^2+−4x^2)= −x^2

(4x+3x) = 7x

(−3+−2) = −5

−x^2 + 7x−5

Answer 2

−x^2+7x−5

Explanation:

---- times this by 1 (3x^2+4x−3) −(4x^2-3x+2) ---- times this by - 1

3x^2+4x−3−4x^2+3x−2

3x^2+4x−3−4x^2+3x−2 - collect like terms

(3x^2+−4x^2)+(4x+3x)+(−3+−2) - solve it

(3x^2+−4x^2)= −x^2

(4x+3x) = 7x

(−3+−2) = −5

−x^2 + 7x−5
