The way to factorise is to find two numbers that multiply together to make 18 but add to make -9. Eighteen doesn't have all that many factor pairs - (1, 18), (2, 9), (3,6) and their negative counterparts. The one we're after is (-3, -6), which just drop into brackets with the s to make ( x − 3 ) ( x − 6 ) . And to to do factorize an equation step by step is 1.Expand the expression and clear all fractions if necessary.
2.Move all terms to the left-hand side of the equal to sign.
3. Factorize the equation by breaking down the middle term.
4.Equate each factor to zero and solve the linear equations.
Lungs = respiration, provides oxygen to the blood.
heart = arteries, pumps blood.
