I'm assuming you mean

we can factor that sum of perfect cubes from

into

so therefor

that is simpliest form
Oh all u do is just do the triangle the subtract the square from that
7. Four and 7 tenths
8. Twenty two and eighty nine hundredths
9. Forty Five and Three hundred Twenty Nine Thousandths
10.Twenty seven hundredths
(x + 8)(x - 6)
to factorise consider the factors of - 48 which sum to + 2
These are + 8 and - 6 thus
x² + 2x - 48 = (x + 8)(x - 6)
