Worksheet on Factoring Simple Quadratics



Practice the worksheet on factoring simple quadratics in the form of x2 + bx + c.

The questions are based on how to factorize the simple quadratic expressions in the form of x2 + bx + c by splitting their co-efficient of middle term.

1. Factorize the following expression:

(i) y2 + 9y + 20

(ii) x2 + 15x + 54

(iii) z2 + 3z - 4

(iv) p2 + 2p - 24

(v) a2 – 5a + 4

(vi) p2 - 15p + 14



2. Resolve into factors:

(i) m2 + 3m - 10

(ii) x2 – 18x - 63

(iii) x2 + 6x + 8

(iv) x2 + 12x + 32

(v) a2 – 8a + 15

(vi) x2 – 12x + 35



3. Factor the middle term:

(i) a2 – 4a – 12

(ii) x2 - 4x - 45

(iii) m2 + 15m + 56

(iv) q2 – 13q + 36

(v) p2 + 5p - 24

(vi) t2 + 17t - 84

(vii) x2 - 15x + 44

(viii) x2 - 5x - 24

(ix) m2 - 4m – 77

(x) x2 – 12x + 20
