Question

-18x²+31x + 35-0
solve by factorisation ​

Answer 1

Answer:

1.Add the numbers

−182+31+35+0

-18x^{2}+31x+35

−182+31+35+0

-18x^{2}+31x+35

2.Common factor

−182+31+35+0

-18x^{2}+31x+35+0

−1(182−31−35)

-1(18x^{2}-31x-35)

3.Use the sum-product pattern

−1(182−31−35)

-1(18x^{2}{-31x}-35)

−1(182+14−45−35)

-1(18x^{2}+{14x}{-45x}}-35)

4.Common factor from the two pairs

−1(182+14−45−35)

-1(18x^{2}+14x-45x-35)

−1(2(9+7)−5(9+7))

-1(2x(9x+7)-5(9x+7))

5.Rewrite in factored form

−1(2(9+7)−5(9+7))

-1(2x(9x+7)-5(9x+7))

−1(2−5)(9+7)
